Description
The Bel SRBC-10E1Ax is part of the non-isolated dc/dc converter series. The modules use a SMT package.
These converters are available in a range of output voltages from 0.75 Vdc to 3.63 Vdc over a wide range of
input voltage (Vin = 4.5 Vdc - 14 Vdc). The efficiency is typically 93% at 3.3 Vdc at output at full load.
