Description

The Bel xRAH-03Hxx0 is part of the low cost non-isolated dc/dc power converter series. It is packaged in a

compact, overmolded package rated at 3 A. Optional lead forming provides a vertical mount product for minimal

footprint or a surface mount option for a very low profile. The output is closely regulated and the efficiency of 3.3

Vdc output is typically 90% at full load. Typical features include remote on/off, input under voltage lockout, over

current protection and short circuit protection.
