Description
The Bel SRBC-16F1Ax 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 (Vin=2.4-5.5V). The
open-frame construction and small footprint enable designers to develop cost and space-efficient solutions.
Standard features include remote On/Off, over current protection, short current protection, wide input, and
programmable output voltage.

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.
