Description

The Bel VRBA-03E1Ax modules are a series of non-isolated dc/dc converters that deliver up to 3 A of output

current with full load efficiency of 93% at 5.0 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. 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.

Part Selection

Notes: 1. These modules use a buck topology, so the output voltages must be 0.5 V less than the input voltage.

Absolute Maximum Ratings

Note: All specifications are typical at 25 °C unless otherwise stated.
