xRAH-01KXxN Series RoHS Compliant Rev.A
• Non-Isolated
• High Efficiency
• Fixed Frequency (400 kHz)
• Low Profile Package
• Remote On/Off
• Active Low
Description
The Bel xRAH-01KXxN is 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
With simulated source impedance
of 500 nH, 5 Hz to 20 MHz; Use one
100 uF/25 V tantalum capacitor and
one 470 uF/35 V electrolytic
capacitor at the input.
