NON-ISOLATED DC/DC CONVERTERS

9.0 Vdc - 18 Vdc Input

5 Vdc - 12 Vdc/1A Output

xRAH-01K Series

RoHS Compliant

Rev.A

• Non-Isolated

• Low Profile Package

• High Efficiency

• Remote On/Off

• Active Low/High

• Fixed Frequency (450kHz)

• UL60950-1 Recognized (UL/cUL)

Description

The Bel xRAH-01Kxxx is a 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 9 Vdc output module is typically 86% at full load.

RoHS Compliance

Complies with the European Directive 2002/95/EC, calling for the elimination of lead and

other hazardous substances from electronic products. These parts are not however

compatible with the higher temperatures associated with lead free solder processes and

must be soldered using a reflow profile with a peak temperature of no more than 240 °C.
