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.

Notes: 1. The max Turn on Voltage threshold of the 3.3 V & 5.0 V output module will be relaxed to 4.9 V & 8.0 V

respectively.

2. The max Turn off Voltage threshold of the 3.3 V output module will be relaxed to 4.5 V. The 5.0 V output

module does not have such function.
