Description
The Bel SRBA-06F2Ax modules are a series of non-isolated dc/dc converters that deliver up to 6 A of output
current with full load efficiency of 93% 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. 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 circuit protection, wide input, and programmable output voltage.

Notes: 1. These modules use a buck topology, so the output voltages must be 0.5 V less than the input voltage.
2. Add “G” to the end of the Model Number 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. SRBA-06F2Ax 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.
