PRODUCT OVERVIEW
CRE1S0505MEC
15
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.

Switching frequency
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.
