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 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 (Vin=3.0 Vdc - 5.5 Vdc). Standard features include remote On/Off, programmable output voltage,
over current protection, over thermal shutdown and short circuit protection.
