Description
The Bel SRBG-30A1A0 is part of the non-isolated dc/dc converter Power Module series. The modules use a SMT
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% at 12 Vdc input and 3.3 Vdc output at full
load.
