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 Vdc output. These modules provide precisely regulated voltage

programmable via external resistor from 0.75 Vdc to 3.63 Vdc over a wide range of input voltage (2.4 Vdc - 5.5

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.

1. These modules use a buck topology, so the output voltages must be 0.8 V less than the input voltage.

2. All part numbers above indicate RoHS 6. Change the second letter "R" to "7" for RoHS 5 part numbers.

3. Add “G” to the end of the Model Number to indicate Tray Packaging.

1. 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 or leave the SEQ pin

floating.
