1. If components are required in tape and reel format suffix order code with -R, e.g. CRE1S0505MC-R.

2. Calculated using MIL-HDBK-217 FN2 and Telcordia SR-332 calculation model with nominal input voltage at full load.

3. UL 60950 recognition does not apply to CRE1S0505MC.

4. 24V input parts prior to date code D1635 have operating temperature range of 0 to 70°C.

All specifications typical at TA=25°C, nominal input voltage and rated output current unless otherwise specified.

PRODUCT OVERVIEW

The CRE1 series are a cost effective 1W DC-DC

converter series, in industry standard packages

with industry standard pinout. Popular input

and output voltages are available. The galvanic

isolation allows the device to be configured to

provide an isolated negative rail in systems where

only positive rails exist. The wide temperature

range guarantees startup from –40°C and full 1

watt output at 85°C3.

FEATURES

UL 60950 recognised3

Single isolated output
