Description

The Bel SRBC-10A2Ax modules are a series of non-isolated dc/dc converters that deliver up to 10 A of output

current with full load efficiency of 93% 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, over current protection, short current protection, wide input, and programmable output voltage.

1. SRBC-10A2Ax 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.
