w R a r A r 4:1 wide input voltage range Features Compact size 1x1 package DC/DC Converter Efficiency up to 90% Wide operating temperature from Regulated -40C to +75C without derating Converters Continuous short circuit protection REC15E-Z Description 15 Watt The REC15E-Z series are 4:1 wide input voltage range 15W power DC/DC converters in a 1x1 case. 3 1 x 1 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 Single and Dual 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 Output where board space is at a premium. Selection Guide Part nom. Input Output Output Efficiency max.
