REC15E-Z

Description

The REC15E-Z series are 4:1 wide input voltage range 15W power DC/DC converters in a 1”x1” case.

Despite their low cost, the converters are fully speciﬁed devices with output currents up to 4 Amps,

no minimum load, 1.6kVDC isolation, high efﬁciency and low ripple/noise ﬁgures.

The inputs are

protected against transients of up to 100V and feature UVLO to allow the primary supply to start up

safely. The single or dual outputs are continuously protected against short circuits and overload and

can drive high capacitive loads. The REC15E-Z series will ﬁnd many uses in cost sensitive applications

where board space is at a premium.
