**MYWGC3R53FFW92RAE** 

## MonoBK™, Multi output DC-DC Converter 

## **Specification Notes** 

(1)Specifications are typical at Ta=+25degC, Vin=typical (+5.0V), Vout1 to 4=typical (+1.2V, +1.8V,+3.3V,+2.5V), full load, external capacitors and natural convection unless otherwise indicated. Extended tests at full power must supply substantial natural airflow. This model is tested and specified with external capacitors shown in the test circuit below. Most capacitors are low ESR types. These capacitors are necessary to accommodate our test equipment and may not be required to achieve specified performance in your applications. However, Murata recommends installation of these capacitors. 

(2)Note that Maximum Power Derating curves indicates an average current at typical input voltage. At higher temperatures and/or lower airflow, the DC/DC converter will tolerate brief full current outputs if the total RMS current over time does not exceed the Derating curve. 

(3)Mean Time Between Failure is calculated by using the Telecordia SR-332 method, Ta=40degC, half output load, natural air convection. 

(4)The On/Off Control Input should use either a switch or an open collector/open drain transistor to connect to GND. A logic gate may also be used by applying appropriate external voltages which do not exceed +Vin 

(5)”Hiccup” overcurrent operation repeatedly attempts to restart the converter with a brief, full-current output. If the overcurrent condition still exists, the restart current will be removed and then tried again. This short current pulse prevents the converter from overheating and damaging the converter. Once the fault is removed, the converter immediately recovers normal operation. 

(6)Output noise may be further reduced by adding an external filter. At zero output current or light load, the output may contain low frequency components which exceed the ripple specification. The output may be operated indefinitely with no load or light load. 

(7)This model is able to start at Ta=-40degC. 

(8)Regulation specifications describe the deviation as the line input voltage or output load current is varied from a nominal midpoint value to either extreme without no load and light load. 

(9)Thermal Protection/Shutdown temperature is measured with the sensor in the converter. (10)Murata can review output specifications and output sequence under customer’s request. Please contact to Murata for details. 

(11)The maximum output capacitive loads depend on the Equivalent Series Resistance (ESR) of the external output capacitors and, to a lesser extent, the distance and series impedance to the load in addition to ambient temperature. Larger capacitance will reduce output noise but may change the transient response. Newer ceramic capacitors with very low ESR may require lower capacitor values to avoid instability. Thoroughly test your capacitors in your applications. For reference, please refer to the “Output Capacitor Design Application Notes”. (12)Do not allow the input voltage to degrade lower than the input under voltage shutdown voltage at all times. Otherwise, you risk having the converter turn off. The under-voltage shutdown is not latching and will attempt to recover when the input is brought back into normal operating range. 

(13)The outputs are not intended to sink appreciable reverse current. (14)When the temperature decreases below the recovery threshold, the converter will automatically restart. 

(15)About di/dt condition, please refer to the table described later. 

(16)The thermal resistance is reference data, and they are measured with our evaluation board as below. 

50.0mm x 101.6mm x 1.6mm (4 Layers, 1oz copper each) FR-4 

(17)Ensured by design. Not production tested. 

(18)This product may not meet the specifications due to Auto PFM/PWM control at light output load. 

(19)Some of product terminal shapes are different from the dimensional drawing because our dicing process might make the product terminal deformed. The deformation length is up to 150um. 

(20)It is recommended to start to operate the I2C functions after the power-on sequence is complete. 

(21)When Vin is ramped up slowly, the sequence may lag 3ms (max.) behind the setting. 

(22)Recommended reflow profile is described in “Soldering Guidelines”.

## **Internal Circuit Diagrams** 

## **ON/OFF Using Guide** 

By using ON/OFF function, the operation of this product can be disabled with supplying input voltage. Power-saving control with the sequence can be easy by using this function. 

ON/OFF control logic 

- ON/OFF pin(1pin) is pull-up                    : Output Voltage = ON 

- ON/OFF pin(1pin) is connected to GND : Output Voltage = OFF

It is strongly recommended that the ON/OFF terminal should be used when turning on/off this product. The characteristics of the ON/OFF function may be affected by turning on/off input voltage. Please check product operation on your application with turning on/off input voltage. 

## **Power Good Signal Using Guide** 

The power good signal terminal should be pulled up to Vin. The resistance value for pulling up is recommended at 10kohm in case that the PG terminal is pulled up to Vin. This product has an open-drain circuit internally. 

## ■PG = High situations 

・ Input voltage is 4.3 to 5.5V and ON/OFF terminal is high. 

・Each output voltage is within its voltage detection threshold (over 90% (typ.))    etc… 

## ■PG=Low situations 

・ ON/OFF pin is low and either output voltage is out of its voltage detection threshold(lower than 80% (typ.)). 

・ During the PG rising delay time after all output are risen. 

・ UVLO is activated. 

・ Over current protection is activated. 

・Over temperature protection is activated. etc…

## MonoBK™, Multi output DC-DC Converter 

## **TECHNICAL NOTES** 

## **Input Fuse** 

Certain applications and/or safety agencies may require fuses at the inputs of power conversion components. Fuses should be also used when there is the possibility of sustained input voltage reversal which is not current limited. For greatest safety, we recommend a fast blow fuse installed in the ungrounded input supply line. The installer must observe all relevant safety standards and regulations. For safety agency approvals, install the converter in compliance with the end-user safety standard. 

## **Input Under-Voltage Shutdown and Start-Up Threshold** 

Under normal start-up conditions, the converter will not begin to regulate properly until the ramping-up input voltage exceeds and remains within the Inout Voltage Range (see Specifications). Once operating, the converter will not turn off until the input voltage drops below the Under-Voltage Shutdown Limit. Subsequent restart will not occur until the input voltage rises again above the Start-Up Threshold. This built-in hysteresis prevents any unstable on/off operation at a single input voltage. Users should be aware however of input sources near the Under-Voltage Shutdown whose voltage decays as input current is consumed (such as capacitor inputs), the converter shuts down and then restarts as the external capacitor recharges. Such situations could oscillate. To prevent this, make sure the operating input voltage is well above the UV Shutdown voltage at all times. 

## **Recommended Output Filtering** 

The converter will achieve its rated output ripple and noise with additional external capacitors. Users may install more external output capacitance to reduce the ripple even further, to improve dynamic response and to ensure the operation stability. Initially we recommend to use low-ESR ceramic (Murata GRM21 series) as described in our circuits. Mount these close to the converter. Check the operation stability with margin and measure the output ripple in your application. If necessary to meet your requested specification, please add the capacitors in parallel up to achieving your requested specification according to Output Capacitor Design Notes. Excessive capacitance can make step load recovery sluggish or possibly introduce instability. Do not exceed the maximum rated output capacitance listed in the specifications. 

## **Output Noise** 

The converter is tested and specified for output noise using designated external output components, circuits and layout as shown in the figures below. In the figure below, the two copper strips simulate real-world printed circuit impedances between the power supply and its load. In order to minimize circuit errors and standardize tests between units, scope measurements should be made using BNC connectors or the probe ground should not exceed one half inch and soldered directly to the test circuit. 

## **Start-Up Time** 

The Startup Time (see Specifications) will vary with input source impedance, external input capacitance, input voltage slew rate and final value of the input voltage as it appears at the converter. 

The converter includes a soft start circuit to moderate the duty cycle of its PFM/PWM controller at power up, thereby limiting the input inrush current. The On/Off Remote Control interval from On command to Vout regulated assumes that the converter already has its input voltage stabilized above the Start-Up Threshold before the On command. The interval is measured from the On command until the output enters and remains within its specified accuracy band. The specification assumes that the output is fully loaded at maximum rated current. Similar conditions apply to the On to Vout regulated specification such as external load capacitance and soft start circuitry. 

## **Recommended Input Filtering** 

Users must assure that the input source has low AC impedance to provide dynamic stability and that the input supply has little or no inductive content, including long distributed wiring to a remote power supply. For best performance, we recommend installing a low-ESR capacitor immediately adjacent to the converter’s input terminals. 

The capacitor should be a ceramic type such as the Murata GRM21 series and an electrolytic type such as Panasonic OS-CON series. Initial suggested capacitor values are 22 uF x 2 ceramic type, rated at twice the expected maximum input voltage. Make sure that the input terminals do not go below the under-voltage shutdown voltage at all times. More input bulk capacitance may be added in parallel (either electrolytic or tantalum) if needed. 

C1= Cout conditions (described in the test circuit for each Vout) C2=OPEN Figure ：Measuring Output Ripple and Noise 

## **Minimum Output Loading Requirements** 

This model regulates within specifications and is stable with the specified load conditions. Operation at no load might however increase output ripple and noise due to PFM control. 

## **Thermal Shutdown** 

To prevent many over temperature problems and damage, the converter includes thermal shutdown circuitry. If environmental conditions cause the temperature rise of the converter above the Operating Temperature Range up to the shutdown temperature, an on-board electronic temperature sensor will power down the unit. When the temperature decreases below the turn-on threshold, the converter will automatically restart. 

**CAUTION:** If you operate too close to the thermal limits, the converter may shut down suddenly without warning. Be sure thoroughly to avoid unplanned thermal shutdown in your application.

## **Temperature Derating Curves** 

The graph in this data sheet illustrates typical operation under a variety of conditions. The derating curve shows the maximum continuous ambient air temperature. Note that these are AVERAGE measurements. 

Note that the temperatures are of the ambient airflow, not the converter itself which is obviously running at higher temperature than the outside air. Also note that very low flow rates (below about 25 LFM) are similar to “natural convection,” that is, not using fan-forced airflow. We use both thermocouples and an infrared camera system to observe thermal performance. 

**CAUTION:** The graph is collected at slightly above Sea Level altitude. Be sure to reduce the derating for higher density altitude. 

## **Output Current Limiting** 

Current limiting inception is defined as the point at which full power falls below the rated tolerance. See the Performance/Functional Specifications. Note particularly that the output current may briefly rise above its rated value in normal operation as long as the average output power is not exceeded. This enhances reliability and continued operation of your application. If the output current is too high, the converter will enter the short circuit condition. 

## **Output Short Circuit Condition** 

When the converter is in current-limit mode, the output voltage will drop as the output current demand increases. Following a time-out period, the converter will restart, causing the output voltage to begin ramping up to its appropriate value. If the short-circuit condition persists, another shutdown cycle will initiate. This rapid on/off cycling is called “hiccup mode”. The hiccup cycling reduces the average output current, thereby preventing excessive internal temperatures and/or component damage. A short circuit can be tolerated indefinitely. 

## **OVP Function** 

This product monitors a feedback voltage to detect over voltage. When the feedback voltage becomes higher than 120% of the target voltage, the circuit operates sink-mode to decrease output voltage. If the output voltage decrease 110% of target voltage, the circuit returns normal operation. 

## **Remote On/Off Control** 

Please refer to the Connection Diagram on page 6 for On/Off connections. The model is enabled when the On/Off pin is pulled high with respect to GND. Positive-polarity devices are disabled when the On/Off is grounded or brought to within a low voltage (see Specifications) with respect to GND. 

Dynamic control of the On/Off function should be able to sink appropriate signal current when brought low and withstand appropriate voltage when brought high. Be aware too that there is a finite time in milliseconds (see Specifications) between the time of On/Off Control activation and stable, regulated output. This time will vary slightly with output load type and current and input conditions. 

## **Output Capacitive Load** 

Users should consider adding capacitance to reduce switching noise and/or to handle spike current load steps. Install enough capacitance to achieve noise objectives. However excess external capacitance may cause regulation problems, degraded transient response and possible oscillation or instability. 

The “hiccup” system differs from older latching short circuit systems because you do not have to power down the converter to make it restart. The system will automatically restore operation as soon as the short circuit condition is removed. 

## **Output Voltage Remote Sense** 

This function is capable to compensate up the voltage drop between the output and input of load. The voltage of the Vout pin must NOT be over their allowed maximum voltage if using the remote sense. The sense trace should be connected to Vout line as shortly as possible. The sense trace should be shielded by GND line or something else to reduce noise pick-up. The powerline length from the product to a sensing point should be within 10cm for output voltage stability. If the remote sense is not needed, the Sense pin should be connected to the Vout pin directly.

## **I2C INTERFACE** 

## **I2C Serial Interface Description** 

The I2C is a two-wire, bidirectional serial interface consisting of a clock line (SCL) and a data line (SDA). The lines are externally pulled to a bus voltage when they are idle. A master device is connected to the lines. Then it generates the SCL signal and device address, and arranges the communication sequence. The interface of the product is an I2C slave that can support fast mode (400kHz). The I2C interface makes it possible to monitor the product status. If the master sends the address as an 8-bit value, the 7-bit address should be followed by 0 or 1 to indicate a read operation. When the I2C is not used, SCL and SDA should be pulled high (5V) by a resistor (4.7kohm). 

## **Transfer Data** 

Data is transmitted in 8-bit bytes through SDA line. Each byte of data should be followed by an acknowledge (ACK) bit. 

## **I2C Update Sequence** 

The product requires a start condition, a valid I2C address, a register address byte and a data byte for a single data update. After receiving each byte, the product acknowledges the byte by pulling the SDA line low during the high period of a SCL pulse. A valid I2C address selects the product. The product performs an update on the falling edge of the LSB byte. Example of I2C read sequence is described below. 

**CAUTION:** When the I2C is not used, SCL and SDA should be pulled high (5V) by a resistor (4.7kohm). 

## **Start and Stop Conditions** 

The start and stop conditions are signaled by the master device, and signify the beginning and the end of the I2C transmission. The start condition is defined as the SDA signal transition from high to low while the SCL is high. The stop condition is defined as the SDA signal transition from low to high while the SCL is high. The master then generates the SCL clocks, and transmits the device address and the Read bit on the SDA line.

*1: If there is a non-negligible parasitic impedance between the power supply and the converter, such as during evaluation, the optional input capacitor “C9” may be required to reduce the impedance. The recommended optional capacitor is an example. Please consider the optimum value for the case. This capacitor is usually an aluminum electrolytic type. It is not necessary to place the capacitor near the input terminal of the converter. This would be typically aluminum electrolytic type and does not need to be close to the input terminals of the converter.
