Description

The Bel VRBC-16F2Ax modules are a series of non-isolated dc/dc converters that can 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. Their open-frame construction and small

footprint enable designers to develop cost and space-efficient solutions. Standard features include remote

ON/OFF, programmable output voltage and over current protection.

Notes

1. VRBC-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.
