Description
The Bel xRAH-05Exx0 is part of the low cost non-isolated dc/dc converter Power Module series. The modules
use a SMD or SIP package for ease of layout and space savings. The output is closely regulated and the
efficiency of 3.3 Vdc output module is typically 91% at full load.

Notes
With simulated source impedance of
500 nH, 5 Hz to 20 MHz. Use one 270
uF/ 16 V OSCON capacitor with
ESR=0.018 ohm max, at 100kHz at
the input
