Description
The Bel xRAH-02C50x is a part of the low cost non-isolated dc/dc converter series. The modules use a SMD or
SIP package for ease of layout and space savings. The output is closely regulated and the efficiency is typically
87% at full load.

Notes: 1. Add “0” suffix at the end of the model number to indicate “Tube Packaging”, and “R” for “Reel
Packaging”, and “G” for “Tray Packaging”.
2. Replace “x” with “0” to allow burst mode operation at low load currents, or with “B” to disable burst
mode operation at light loads.
