Description
The Bel VRBC-16F1Ax 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). 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 0.8 V less than the input voltage.
2. Change the last character “L” to “C” to indicate 0.20’’ pin length.
3. “W” indicates special coating.
4. Add “G” to the end of the Model Number to indicate Tray Packaging.
5. All part numbers above indicate RoHS 6. Change the second letter "R" to "7" for RoHS 5 part numbers.
