Description
The Bel VRBG-30A1A1 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 0.8 Vdc to 3.63 Vdc over a wide
range of input voltage (Vin = 8 Vdc - 14 Vdc).The efficiency is typically 92.5% at 12 Vdc input and 3.3 Vdc output
at full load.
