Description
The Bel VRBC-10A1Ax modules are series of the non-isolated dc/dc converters. The modules use a SIP package.
These converters are available in a range of output voltages from 0.75 Vdc to 5.0 Vdc over a wide range of input
voltage (Vin = 8.3 Vdc - 14 Vdc).The efficiency is typically 95%@5.0 Vout at full load.
