Description

The Bel SRBA-03F1Ax modules are a series of non-isolated dc/dc converters that deliver up to 3 A of output

current with full load efficiency of 94% 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). 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, under-

voltage lockout, over temperature protection 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.
