Description
The Bel VRBA-06F1Ax modules are a series of non-isolated dc/dc converters that deliver up to 6A of output
current with full load efficiency of 93% at 3.3 V output. These modules provide precisely regulated voltage
programmable via external resistor from 0.75 V to 3.63 V over a wide range of input voltage (2.4 V-5.5 V). 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 circuit protection, wide input, and
programmable output voltage.

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” suffix at the end of the model number to indicate Tray Packaging.
