Description
The Bel VRBC-10F2Ax modules are a series of non-isolated dc/dc converters that deliver up to 10 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. The open-frame construction and small
footprint enable designers to develop cost and space-efficient solutions. Standard features include remote
On/Off, remote sense, over current protection, short current 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” to the end of the Model Number to indicate Tray Packaging.
