The Bel VRP1-30E1A0 is part of the non-isolated DC-DC converter Power Module series. The modules use a SIP package. These converters are available in a range of output voltages from 0.591 VDC to 5.1 VDC over a wide range of input voltage (Vin = 4.5 - 13.8 VDC). The efficiency is typically 94% @ 12Vin and 5.0 Vout at full load.
