Description
The Bel xRBA-06E2Ax modules are a series of non-isolated dc/dc converters that can 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 5.0 Vdc 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.

Notes: 1. These modules use a buck topology, so the output voltages must be 0.5 V less than the input voltage.
2. Use “0” to replace “x” for remote on/off active high logic and use “L” for active low logic. Change the
last character “L” to “C” to indicate 0.20’’ pin length. Add “G” suffix at the end of the model numbers to
indicate Tray Packaging.
3. All part numbers above indicate RoHS 6. Change the second letter "R" to "7" for RoHS 5 part numbers.

1. xRBA-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.
