NON-ISOLATED DC/DC CONVERTERS 2.4 V-5.5 V Input 0.75 V-3.63 V/16 A Output SRBC-16F2Ax Series • • • • • • • Non-Isolated High Efficiency High Power Density Fixed Frequency (300 kHz) OCP/SCP Flexible Output Voltage Sequencing Remote On/Off RoHS Compliant • • • • • • • Under-voltage Lockout (UVLO) Over Temperature Protection Wide Input Range Wide Trim Range Remote Sense Converter can sink and source current Active Low/High (option) Description The Bel SRBC-16F2Ax modules are a series of non-isolated dc/dc converters that deliver up to 16 A of output current with full load efficiency of 94% at 3.3 V output. These modules provide precisely regulated voltage programmable via external resistor from 0.75 V to 3.63 V over a wide range of input voltage (2.4-5.5 V). 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 Voltage 0.75 V-3.63 V 1 Input Voltage 2.4 V-5.5 V Max. Output Current 16 A Max. Output Power 58.1 W Typical Efficiency 94% Model Number Active Low SRBC-16F2AL Model Number Active High SRBC-16F2A0 Model Number Active Low SRBC-16F2AW 2 Notes: 1. These modules use a buck topology, so the output voltages must be 0.8 V less than the input voltage. 2. “W” indicates special coating. 3. Add “G” to the end of the Model Number to indicate Tray Packaging.

SRBC-16F2Ax 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.
