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.

Notes:

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

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

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