Description
The Bel VRBC-16E1Ax is part of the non-isolated dc/dc converter series. The modules use a SIP 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 92% at 3.3 Vdc output at full load.
