Description
The Bel VRBC-16F2Ax 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). These modules have a sequencing feature that enables designers to implement various types of output
voltage sequencing when powering multiple voltages on a board. 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. All part numbers above indicate RoHS 6. Change the second letter "R" to "7" for RoHS 5 part numbers.
3. Add “G” to the end of the Model Number to indicate Tray Packaging.

1. VRBC-16F2Ax series of modules include a sequencing feature that enables users to implement various
types of output voltage sequencing in their applications. This is accomplished via an additional
sequencing pin. When the sequencing feature is not used, tie the SEQ pin to Vin or leave the SEQ pin
floating.
