Description
The Bel VRPG-22A1AE is part of the low cost non-isolated dc/dc converter power module series. The module use
a SIP package for ease of layout and space savings. The output is closely regulated and can be trimmed from
1.23 Vdc to 3.3 Vdc over a wide range of input voltage (Vin=10.8 Vdc-13.2 Vdc). The efficiency is typically 79%
at 1.23 Vdc output at full load. Typical features include remote on/off, under-voltage lockout, over-current
protection and short circuit protection.
