## **NON-ISOLATED DC/DC CONVERTERS** **8.3 Vdc - 14 Vdc Input 0.75 Vdc - 5.0 Vdc/16 A Output** ## **SRBC-16A2Ax RoHS Compliant Rev.A** - Non-Isolated - High Efficiency - High Power Density - Excellent Thermal Performance - Low Cost - Flexible Output Voltage Sequencing - Able to Sink & Source Current - Vout Prebias - Under-voltage Lockout (UVLO) - Over Temperature Protection - - OCP/SCP - - Wide Input - Wide Trim - Remote On/Off - Active Low/High (Option) - Remote Sense - Industrial Temperature Range ## **Description** The Bel SRBC-16A2Ax modules are a series of non-isolated dc/dc converters that deliver up to 16 A of output current with full load efficiency of 92% at 3.3 Vdc output. These modules provide precisely regulated voltage programmable via external resistor from 0.75 Vdc to 5.0 Vdc over a wide range of input voltage (8.3 Vdc - 14 Vdc). These modules have a sequencing feature that enables designers to implement various types of output voltage sequencing when powering multiple voltages on a board. The open-frame construction and small footprint enable designers to develop cost and space-efficient solutions. Standard features include remote On/Off, remote sense, over current protection, short current protection, wide input, and programmable output voltage. ## **Part Selection** |**Output**<br>**Voltage**|**Input**<br>**Voltage**|**Max.

SRBC-16A2Ax series of modules include a sequencing feature that enables users to implement various types of output voltage sequencing in their applications. This is accomplished via an additional sequencing pin. When the sequencing feature is not used, tie the SEQ pin to Vin or leave it unconnected. **Bel Fuse Inc.** 206 Van Vorst Street, Jersey City, NJ 07302 • Tel 201-432-0463 • Fax 201-432-9542 • www.belfuse.com ## **NON-ISOLATED DC/DC CONVERTERS 8.3 Vdc - 14 Vdc Input 0.75 Vdc - 5.0 Vdc/16 A Output** ee ## **Input Specifications** |**Parameter **|**Min**|**Typ**|**Max **|**Notes**| |---|---|---|---|---| |Input Voltage<br>Vo, set≤3.63 V<br>Vo,set>3.63 V|8.3 V<br>8.3 V|12 V<br>12 V|14 V<br>13.2 V|| |Input Current (full load)|-|-|11 A|| |Input Current (no load)|-|100 mA|-|| |Remote Off Input Current|-|2 mA|-|| |Input Reflected Ripple Current (pk-pk)|-|70 mA|200 mA|Tested with one 1000 uF/25 V AL input<br>capacitor with ESR=0.03 ohm max and 6<br>×47 uF/16 V tantalum capacitors with<br>ESR=0.013 ohm max at 100 kHz, &<br>simulated source impedance of 1000 nH,<br>5 Hz to 20 MHz.| |Input Reflected Ripple Current (rms)|-|-|150 mA|| |I2t Inrush Current Transient|-|0.2 A2s|0.4 A2s|| |Turn-on Voltage Threshold|-|8.0 V|-|| |Turn-off Voltage Threshold|-|7.5 V|-|| ## **Output Specifications** |**Parameter **<br>~~Se~~|**Parameter **<br>~~Se~~|**Min**|**Min**|**Typ**|**Typ**|**Max **|**Max **|**Notes**| |---|---|---|---|---|---|---|---|---| |Output Voltage Set Point<br>~~Se~~||-2% Vo,set||-||2% Vo,set||Vin=12 V, full load| |Load Regulation<br>~~Se~~<br>~~a~~||-||0.1% Vo,set||-||Io=Io, min to Io, max| |Line Regulation<br>~~ee~~<br>~~oo~~||-<br>~~ee~~||0.1% Vo,set<br>~~ee~~||-<br>~~ee~~||Vin=Vin, min to Vin, max<br>~~eT~~| |Regulation Over Temperature<br>(-40 °C to+85 °C)<br>~~ee~~<br>~~oo~~||-<br>~~ee~~||0.3% Vo,set<br>~~ee~~||-<br>~~ee~~||Tref=Ta, min to Ta, max<br>~~eT~~| |Output Current<br>~~ee~~<br>~~oo~~<br>~~a~~||0 A<br>~~ee~~||-<br>~~ee~~||16 A<br>~~ee~~||~~eT~~| |Current Limit Threshold||-||180% Io||-||| |Short Circuit Surge Transient<br>~~a~~||-<br><br>~~ee~~||1 A2s<br><br>~~ee~~||3 A2s<br><br>~~ee~~||| |Ripple and Noise (pk-pk)<br>~~**e**~~||-<br>~~**e**~~<br>~~ee~~<br>~~ee~~||75 mV<br>~~**e**e~~<br>~~ee~~||100 mV<br>~~e~~<br>~~ee~~||Tested with 0-20 MHz, 10 uF<br>tantalum capacitor & 1 uF TDK<br>ceramic capacitor at the output<br>~~e~~| |Ripple and Noise (rms)<br>~~**e**~~||-<br>~~**e**~~<br>~~ee~~<br>~~e~~<br>~~ee~~||30 mV<br>~~**e**e~~<br>~~ee~~<br>~~e~~||45 mV<br>~~e~~<br>~~ee~~<br>~~e~~||| |Turn on Time<br>~~en~~||-<br>~~ee~~<br>~~ee~~<br>~~en~~||6 mS<br>~~ee~~<br>~~en~~||10 mS<br>~~ee~~<br>~~en~~||~~en~~| |Overshoot at Turn on<br>~~a~~||-<br>~~ee ~~||-<br> ~~ee ~~||1% Vo,set<br> ~~ee~~||| |Output Capacitance<br>~~TT~~||-||-||5000 uF||| |**Transient Response**<br>~~TT~~<br>~~oO~~<br>~~re~~<br>~~ee~~<br>~~oo~~||||||||| |50% ~ 100% Max Load<br>~~TT~~<br>~~oO~~<br>~~oo~~<br>~~oo~~|VO=0.75 V -<br>5.0 V||-<br>~~re~~||100 mV<br>~~re~~<br>~~ee~~<br>~~ee~~||-<br>~~re~~|di/dt=2.5 A/uS; Vin=12 V; and<br>with 2×150 uF polymer<br>capacitors at the output| |Settling Time<br>~~oO~~<br>~~oo~~<br>~~oo~~<br>~~oo~~|||-<br>~~re~~<br>~~ee~~||50 uS<br>~~re~~<br>~~ee~~<br>~~ee~~<br>~~ee~~<br>~~**ee**~~||-<br>~~re~~<br>~~ee~~|| |100% ~ 50% Max Load<br>~~oo~~<br>~~oo~~<br>~~oo~~|||-<br>~~ee~~||100 mV<br>~~ee~~<br>~~ee~~<br>~~ee~~<br>~~**ee**~~||-<br>~~ee~~|| |Settling Time<br>~~oo~~<br>~~oo~~|||-<br>~~rs~~||50 uS<br>~~ee~~<br>~~**ee**~~<br>~~rs~~||-<br>~~rs~~|| **Note** : All specifications are typical at nominal input, full load at 25 °C unless otherwise stated. **Bel Fuse Inc.** 206 Van Vorst Street, Jersey City, NJ 07302 • Tel 201-432-0463 • Fax 201-432-9542 • www.belfuse.com ## **NON-ISOLATED DC/DC CONVERTERS** **8.3 Vdc - 14 Vdc Input 0.75 Vdc - 5.0 Vdc/16 A Output** ## **General Specifications** |**Parameter **|**Min**|||**Typ**||**Max **|**Notes**| |---|---|---|---|---|---|---|---| |Efficiency|||||||| |Vo=5.0 V|-|||94%||-|| |Vo=3.3 V|-|||92%||-|| |Vo=2.5 V<br>Vo=1.8 V|-<br>-|||90%<br>88%||-<br>-|Measured at Vin=12 V, full load| |Vo=1.5 V|-|||87%||-|| |Vo=1.2 V|-|||85%||-|| |Vo=0.75 V|-|||79%||-|| |Switching Frequency|265 kHz|||300 kHz||335 kHz|| |Over Temperature Shutdown1|-|||130°C||-|| |Output Trim Range (Wide Trim)|0.7525 V|0.7525 V||-||5 V|| |Remote Sense Compensation|-|||-||0.5 V|| |MTBF||2,666,488 hours|||||Calculated Per Bell Core SR-332 (IO=80%<br>Io,max; Vo=5 V; Vin=12 V; Ta= 25°C)| |Dimensions|||||||| |Inches (L×W×H)||1.30 x 0.53 x 0.315||1.30 x 0.53 x 0.315|||| |Millimeters (L×W×H)||33.02 x 13.46 x 8.00|||33.02 x 13.46 x 8.00||| |Weight|-|||8 g||-|| **Notes** : All specifications are typical at 25 °C unless otherwise stated. 1.

About Novapart
Novapart is a B2B electronic component broker specialising in stock shortages and cost reduction. We source hard-to-find parts and identify compliant alternatives across a catalogue of 410,000+ components from 500+ manufacturers.
Learn more →Stock Shortage Specialist
When a component is unavailable, discontinued or has an unacceptable lead time, we tap into our network of vetted European and Asian distributors to source what you need — without compromising on quality or traceability.
Request a quote →Compliant Alternatives
We identify pin-to-pin, electrically equivalent substitutes that meet the same certifications (RoHS, AEC-Q100, REACH) as your original specification — validated against datasheets, not just part numbers. Often at a lower cost.
