Datasheet
Bel Power Solutions point-of-load converters are recommended for use with regulated bus converters in an Intermediate Bus Architecture (IBA). The YNV12T16 non-isolated DC-DC converters deliver up to 16 A of output current in an industry-standard, through-hole (SIP) package. They operate from a 9.6 to 14 VDC input and are ideal choices for Intermediate Bus Architectures where point-of-load power delivery is generally a requirement. In addition, they provide a resistor-programmable regulated output voltage of 0.7525 V to 5.5 V. The Y Series of non-isolated DC-DC converters provides exceptional thermal performance, even in high temperature environments with minimal airflow. This is accomplished through the use of circuit, packaging and processing techniques to achieve ultra-high efficiency, excellent thermal management and a very sleek body profile. - RoHS lead-free solder and lead-solder-exempted products are available - Delivers up to 16 A (88 W) The low body profile and the preclusion of heat sinks minimize impedance to system airflow, thus enhancing cooling for both upstream and downstream devices. The use of 100% automation for assembly, coupled with advanced power electronics and thermal design, results in a product with extremely high reliability. - Extended input range 9.6 V – 14 V - Industry-standard footprint and pinout - Single-in-Line Package (SIP): 2.0” x 0.575” x 0.307” (50.8 x 14.59 x 7.80 mm) - Weight: 0.25 oz [7 g] - Synchronous Buck Converter Topology - Start-up into pre-biased output - No minimum load required - Programmable output voltage via external resistor - Operating ambient temperature: -40 °C to 85 °C - Remote output sense - Intermediate Bus Architectures - Telecommunications - Data Communications - Distributed Power Architectures - ▪ Servers, Workstations - Remote ON/OFF (Positive or Negative) - Fixed-frequency operation - Auto-reset output overcurrent protection - Auto-reset overtemperature protection - High reliability, MTBF = TBD Million Hours - All materials meet UL94, V-0 flammability rating - High efficiency – no heat sink required - Reduces Total Solution Board Area - ▪ Minimizes Part Numbers in Inventory - Safety approved to UL/CSA 62368-1 and EN/IEC 62368-1 **==> picture [229 x 42] intentionally omitted <==** **----- Start of picture text -----**<br> eiEee Del Skk::POWER<br>**----- End of picture text -----**<br> 2 ## YNV12T16 DC-DC Converter Conditions: TA = 25 ºC, Airflow = 200 LFM (1 m/s), Vin = 12 VDC, Vout = 0.7525 – 5.5 V, unless otherwise specified. |**PARAMETER**|**NOTES**|**MIN**|**TYP**|**MAX**|**UNITS**| |---|---|---|---|---|---| |**ABSOLUTE MAXIMUM RATINGS**|||||| |Input Voltage|Continuous|-0.3||15|VDC| |Operating Ambient Temperature||-40||85|°C| |Storage Temperature||-55||125|°C| |**FEATURE CHARACTERISTICS**|||||| |Switching Frequency|||300||kHz| |Output Voltage Programming Range1|By external resistor, See Trim Table 1|0.7525||5.5|VDC| |Remote Sense Compensation1||||0.5|VDC| |Turn-On Delay Time2|Full resistive load||||| |With Vin = (Converter Enabled, then Vin applied)|From Vin = Vin(min) to Vo=0.1* Vo(nom)||3.5||ms| |With Enable (Vin = Vin(nom) applied, then enabled)|From enable to Vo= 0.1*Vo(nom)||3.5||ms| |Rise time2|From 10% to 90%, full resistive load||3.5||ms| |ON/OFF Control (Positive Logic)3|Converter Off<br>Converter On|-5<br>2.4||0.8<br>VIN|VDC<br>VDC| |ON/OFF Control (Negative Logic)3|Converter Off<br>Converter On|2.4<br>-5||VIN<br>0.8|VDC<br>VDC| |**INPUT CHARACTERISTICS**|||||| |Operating Input Voltage Range||9.6|12|14|VDC| ||Turn-on Threshold||9||VDC| |Input Under Voltage Lockout|Turn-off Threshold||8.5||VDC| |Maximum Input Current|16 ADC Out @ 9.6 VDC In||||| ||VOUT= 5.0 VDC|||9|ADC| ||VOUT= 3.3 VDC|||6|ADC| ||VOUT= 2.5 VDC|||4.7|ADC| ||VOUT= 2.0 VDC|||3.8|ADC| ||VOUT= 1.8 VDC|||3.5|ADC| ||VOUT= 1.5 VDC|||3.0|ADC| ||VOUT= 1.2 VDC|||2.5|ADC| ||VOUT= 1.0 VDC|||2.1|ADC| |Input Stand-by Current (Converter disabled)|||5||mA| |Input No Load Current (Converter enabled)|VOUT= 5.0 VDC||80||mA| ||VOUT= 3.3 VDC||60||mA| ||VOUT= 2.5 VDC||52||mA| ||VOUT= 2.0 VDC||45||mA| ||VOUT= 1.8 VDC||43||mA| ||VOUT= 1.5 VDC||40||mA| ||VOUT= 1.2 VDC||37||mA| ||VOUT= 1.0 VDC||35||mA| ||VOUT= 0.7525 VDC||33||mA| |Input Reflected-Ripple Current - is|See Fig. E for setup.

In many applications, the inductance associated with the distribution from the power source to the input of the converter can affect the stability of the converter. It is recommended to use decoupling capacitors in order to ensure stability of the converter and reduce input ripple voltage. The converter has an internal input capacitance of 32 μ F with very low ESR ceramic capacitors. In a typical application, low - ESR tantalum or POS capacitors will be sufficient to provide adequate ripple voltage filtering at the input of the converter. However, very low ESR ceramic capacitors 47 μ F-100 μ F are recommended at the input of the converter in order to minimize the input ripple voltage. They should be placed as close as possible to the input pins of the converter. The YNV12T16 has been designed for stable operation with or without external capacitance. Low ESR ceramic capacitors (minimum 47 μ F) placed as close as possible to the load are recommended for improved transient performance and lower output voltage ripple. It is important to keep low resistance and low inductance PCB traces when the connecting load to the output pins of the converter in order to maintain good load regulation. ## **ON/OFF (Pin 10)** The ON/OFF pin is used to turn the power converter on or off remotely via a system signal. There are two remote control options available, positive logic (standard option) and negative logic, and both are referenced to GND. Typical connections are shown in Fig. A. The positive logic version turns the converter on when the ON/OFF pin is at a logic high or left open, and turns the converter off when at a logic low or shorted to GND. **==> picture [227 x 96] intentionally omitted <==** **----- Start of picture text -----**<br> Vin Nex TM -v Series SENSE<br>Converter<br>R*<br>(Top View) Vout<br>ON/OFF<br>Vin<br>TRIM<br>Rload<br>6 5<br>GND GND<br>CONTROL<br>INPUT<br>R* is for negative logic option only<br>**----- End of picture text -----**<br> Fig. A: Circuit configuration for ON/OFF function. The negative logic version turns the converter on when the ON/OFF pin is at a logic low or left open, and turns the converter off when the ON/OFF pin is at a logic high or connected to Vin. The ON/OFF pin is internally pulled-up to Vin for a positive logic version, and pulled-down for a negative logic version. A TTL or CMOS logic gate, open collector (open drain) transistor can be used to drive ON/OFF pin. When using an open collector (open drain) transistor with a negative logic option, add a pull-up resistor (R*) of 75 k Ω to Vin as shown in Fig. A; This device must be capable of: - sinking up to 0.2 mA at a low level voltage of 0.8 V - sourcing up to 0.25 mA at a high logic level of 2.3V – 5V - sourcing up to 0.75 mA when connected to Vin ## **Remote Sense (Pin 3)** The remote sense feature of the converter compensates for voltage drops occurring only between Vout pin of the converter and the load. The SENSE (Pin 3) pin should be connected at the load or at the point where regulation is required (see Fig. B). There is no sense feature on the output GND return pin, where a solid ground plane is recommended to provide a low voltage drop. If remote sensing is not required, the SENSE pin must be connected to the Vout pin to ensure the converter will regulate at the specified output voltage. If these connections are not made, the converter will deliver an output voltage that is slightly higher than the specified value. tech.support@psbel.com 5 YNV12T16 DC-DC Converter **==> picture [222 x 92] intentionally omitted <==** **----- Start of picture text -----**<br> Vin Nex TM -v Series SENSE<br>Converter<br>(Top View) Vout Rw<br>ON/OFF<br>Vin<br>TRIM Rload<br>6 5<br>GND GND<br>Rw<br>Fig. B: Remote sense circuit configuration.<br>**----- End of picture text -----**<br> Because the sense lead carries minimal current, large trace on the end-user board is not required. However, the sense trace should be located close to a ground plane to minimize system noise and insure optimum performance. When utilizing the remote sense feature, care must be taken not to exceed the maximum allowable output power capability of the converter, equal to the product of the nominal output voltage and the allowable output current for the given conditions. When using remote sense, the output voltage at the converter can be increased up to 0.5 V above the nominal rating in order to maintain the required voltage across the load. Therefore, the designer must, if necessary, decrease the maximum current (originally obtained from the derating curves) by the same percentage to ensure the converter’s actual output power remains at or below the maximum allowable output power. ## **Output Voltage Programming (Pin 9)** The output voltage can be programmed from 0.7525 V to 5.5 V by connecting an external resistor between the TRIM pin (Pin 9) and the GND pin (Pin 5); see Fig. C. A trim resistor, RTRIM, for a desired output voltage can be calculated using the following equation: **==> picture [196 x 24] intentionally omitted <==** where, **RTRIM** = Required value of trim resistor [k ] **VO** − **REQ** = Desired (trimmed) output voltage [V] **==> picture [223 x 62] intentionally omitted <==** **----- Start of picture text -----**<br> Vin Nex TM -v Series SENSE<br>Converter<br>(Top View) Vout<br>ON/OFF<br>Vin<br>TRIM<br>6 GND GND 5 RTRIM Rload<br>**----- End of picture text -----**<br> Fig. C: Configuration for programming output voltage. Note that the tolerance of a trim resistor directly affects the output voltage tolerance. It is recommended to use standard 1% or 0.5% resistors; for tighter tolerance, two resistors in parallel are recommended rather than one standard value from Table 1. The ground pin of the trim resistor should be connected directly to the converter GND pin (Pin 5) with no voltage drop in between. Table 1 provides the trim resistor values for popular output voltages. **==> picture [17 x 35] intentionally omitted <==** **----- Start of picture text -----**<br> 1p ag<br>ality<br>**----- End of picture text -----**<br> **Asia-Pacific Europe, Middle East North America** +86 755 298 85888 +353 61 225 977 +1 408 785 5200 © 2020 Bel Power Solutions & Protection BCD.00679_C BCD.00679_C 6 ## YNV12T16 DC-DC Converter |**V0-REG [V]**|**RTRIM [kΩ] **|**The Closest Standard**<br>**Value [kΩ] **| |---|---|---| |0.7525|open|| |1.0|41.2|41.2| |1.2|22.46|22.6| |1.5|13.0|13.0| |1.8|9.0|9.09| |2.0|7.4|7.32| |2.5|5.0|4.99| |3.3|3.12|3.09| |5.0|1.47|1.47| |5.5|1.21|1.21| Table 1: Trim Resistor Value The output voltage can also be programmed by an external voltage source.

The converter will shut down when the input voltage drops below a pre-determined voltage; it will start automatically when Vin returns to a specified range. The input voltage must be at least 9.6 V (typically 9 V) for the converter to turn on. Once the converter has been turned on, it will shut off when the input voltage drops below typically 8.5 V. ## **Output Overcurrent Protection (OCP)** The converter is protected against overcurrent and short-circuit conditions. Upon sensing an overcurrent condition, the converter will enter hiccup mode. Once the overload or short-circuit condition is removed, Vout will return to nominal value. tech.support@psbel.com 7 ## YNV12T16 DC-DC Converter ## **Overtemperature Protection (OTP)** The converter will shut down under an overtemperature condition to protect itself from overheating caused by operation outside the thermal derating curves, or operation in abnormal conditions such as system fan failure. After the converter has cooled to a safe operating temperature, it will automatically restart. ## **Safety Requirements** Approved to the latest edition and amendment of ITE Safety standards, UL/CSA 62368-1 and EN/IEC 62368-1. The maximum DC voltage between any two pins is Vin under all operating conditions. Therefore, the unit has ELV (extra low voltage) output; it meets ES1 requirements under the condition that all input voltages are ELV. The converter is not internally fused. To comply with safety agencies requirements, a recognized fuse with a maximum rating of 15 Amps must be used in series with the input line. ## **General Information** The converter has been characterized for many operational aspects, to include thermal derating (maximum load current as a function of ambient temperature and airflow) for vertical mounting, efficiency, start-up and shutdown parameters, output ripple and noise, transient response to load step-change, overload and short circuit. The figures are numbered as Fig. x.y, where x indicates the different output voltages, and y associates with specific plots (y = 1 for the vertical thermal derating, …). For example, Fig. x.1 will refer to the vertical thermal derating for all the output voltages in general. The following pages contain specific plots or waveforms associated with the converter. Additional comments for specific data are provided below. ## **Test Conditions** All thermal and efficiency data presented were taken with the converter soldered to a test board, specifically a 0.060” thick printed wiring board (PWB) with four layers. The top and bottom layers were not metalized. The two inner layers, comprising two-ounce copper, were used to provide traces for connectivity to the converter. The lack of metalization on the outer layers as well as the limited thermal connection ensured that heat transfer from the converter to the PWB was minimized. This provides a worst-case but consistent scenario for thermal derating purposes. All measurements requiring airflow were made in vertical and horizontal wind tunnel facilities using Infrared (IR) thermography and thermocouples for thermometry. Ensuring components on the converter do not exceed their ratings is important to maintaining high reliability. If one anticipates operating the converter at or close to the maximum loads specified in the derating curves, it is prudent to check actual operating temperatures in the application. Thermographic imaging is preferable; if this capability is not available, then thermocouples may be used. Bel Power Solutions recommends the use of AWG #40 gauge thermocouples to ensure measurement accuracy. Careful routing of the thermocouple leads will further minimize measurement error.

Ambient temperature was varied between 25 °C and 85 °C, with airflow rates from 30 to 500 LFM (0.15 m/s to 2.5 m/s), and vertical converter mounting. The airflow during the testing is parallel to the long axis of the converter, going from input pins to output pins. For each set of conditions, the maximum load current was defined as the lowest of: - (i) The output current at which any MOSFET temperature does not exceed a maximum specified temperature 120 °C) as indicated by the thermographic image, or - (ii) The maximum current rating of the converter (16 A) During normal operation, derating curves with maximum FET temperature less than or equal to 120 °C should not be exceeded. Temperature on the PCB at the thermocouple location shown in Fig. D should not exceed 120 °C in order to operate inside the derating curves. Fig. D: Location of the thermocouple for thermal testing. ## **Efficiency** Figure x.2 shows the efficiency vs. load current plot for ambient temperature of 25 ºC, airflow rate of 200 LFM (1 m/s) and input voltages of 9.6 V, 12 V and 14 V. ## **Power Dissipation** Fig. x.3 shows the power dissipation vs. load current plot for Ta = 25 ºC, airflow rate of 200 LFM (1 m/s) with vertical mounting and input voltages of 9.6 V, 12 V and 14 V. ## **Ripple and Noise** The output voltage ripple waveform is measured at full rated load current. Note that all output voltage waveforms are measured across a 1 F ceramic capacitor. The output voltage ripple and input reflected ripple current waveforms are obtained using the test setup shown in Figure E. **==> picture [304 x 80] intentionally omitted <==** **----- Start of picture text -----**<br> i<br>—_ S ><br>1 H TM<br>Nex -v Series<br>inductancesource CIN 1 F CO<br>V source ceramic 4x47 F ConverterDC/DC capacitorceramic capacitorceramic 100 F Vout<br>capacitor<br>**----- End of picture text -----**<br> Fig. E: Test setup for measuring input reflected ripple currents, is and output voltage ripple tech.support@psbel.com 9 YNV12T16 DC-DC Converter **==> picture [480 x 388] intentionally omitted <==** **----- Start of picture text -----**<br> 20<br>16<br>tt |<br>12 SSK<br>500 LFM (2.5 m/s)<br>8<br>400 LFM (2.0 m/s)<br>300 LFM (1.5 m/s)<br>200 LFM (1.0 m/s)<br>4 100 LFM (0.5 m/s)<br> 30 LFM (0.15 m/s)<br>-eL<br>0 Fre]<br>| tt<br>20 30 40 50 60 70 80 90<br>Ambient Temperature [°C]<br>Fig. 5.0V.1: Available load current vs. ambient temperature and airflow rates for Vout = 5.0 V converter mounted vertically<br>with Vin = 12 V, and maximum MOSFET temperature 120 C.<br>1.00 6<br>5<br>0.95<br>4<br>0.90 = a,an<br>3 PK<br>0.85<br>14 V 2 14 V<br>12 V 12 V<br>9.6 V 9.6 V<br>0.80<br>1 len<br>0.75 Pe) 0 ae<br>=F | | tT<br>0 3 6 9 12 15 18 0 3 6 9 12 15 18<br>Load Current [Adc] Load Current [Adc]<br>Fig. 5.0V.2: Efficiency vs. load current and input voltage for Fig. 5.0V.3: Power loss vs. load current and input voltage for<br>Vout = 5.0 V converter mounted vertically with air flowing at Vout = 5.0 V converter mounted vertically with air flowing at<br>a rate of 200 LFM (1 m/s) and Ta = 25 C. a rate of 200 LFM (1 m/s) and Ta = 25 C.<br>Load Current [Adc]<br>Efficiency<br>Power Dissipation [W]<br>**----- End of picture text -----**<br> Fig. 5.0V.4: Turn-on transient for Vout = 5.0 V with application of Vin at full rated load current (resistive) and 100 _μ_ F external capacitance at Vin = 12 V.
