Description
The Bel VRBA-06A2Ax modules are a series of non-isolated dc/dc converters that deliver up to 6 A of output
current with full load efficiency of 92% at 5.0 Vdc output. These modules provide precisely regulated voltage
programmable via external resistor from 0.75 Vdc to 5.5 Vdc over a wide range of input voltage (8.3 Vdc - 14
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,
over current protection, short current protection, wide input, and programmable output voltage.

1. VRBA-06A2Ax 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.
