Description
The Bel xRAH-03Exx0 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 93% at full load.

Notes
Min. input voltage for 5.0 V output module
should be 8.0 V
With simulated source impedance of
500 nH, 5 Hz to 20 MHz; Use two
270 uF/16 V Oscon capacitors with ESR =
0.018 ohm max. at 100 kHz at 25 °C
Not applicable for 5.0 V output.
