Description  
The Bel VRBA-03E1Ax modules are a series of non-isolated dc/dc converters that deliver up to 3 A of output  
current with full load efficiency of 93% at 5.0 V output. These modules provide precisely regulated voltage  
programmable via external resistor from 0.75 V to 5.0 V over a wide range of input voltage. 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. Add “G” to the end of the Model Number to indicate Tray Packaging.
