Description
The Bel V7BC-16F2Ax modules are a series of non-isolated DC/DC converters that can deliver up to 16A of
output current with full load efficiency of 94% at 3.3V output. These modules provide precisely regulated voltage
programmable via external resistor from 0.75Vdc to 3.63Vdc over a wide range of input voltage(2.4V-5.5V).
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.

1. V7BC-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.
