Description
The Bel x7BA-06E2Ax modules are a series of non-isolated DC/DC converters that can deliver up to 6A of
output current with full load efficiency of 92% at 5.0V output. These modules provide precisely regulated voltage
programmable via external resistor from 0.75V to 5.0V over a wide range of input voltage. 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.

Note
: 1. x7BA-06E2Ax 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.
