Description
The Bel xRPB-06F1Ax modules are a series of non-isolated high density open frame dc/dc converters that can
deliver up to 6 A of output current with full load efficiency of 94% at 3.3 V output. These modules provide
precisely regulated voltage programmable via external resistor from 0.75 V to 3.63 V over a wide range of input
voltage (Vin=3.0 V-5.5 V). Standard features include remote On/Off, programmable output voltage, over current
protection, over thermal shutdown and short circuit protection.
