www.murata-ps.com NPH15S Series Isolated 15W Single Output DC/DC Converters FEATURES „ RoHS compliant „ High efficiency to 89% „ Power density up to 2.4W/cm3 „ UL 94V-0 package material „ Industry standard pinout „ UL 1950 recognized „ Non latching current limit „ Constant 350kHz frequency „ 1.5kV input to output isolation „ Versatile control options „ Continuous rating to 30W at 40ºC without heatsink „ Operation to zero load „ Protected against load faults „ Internal over temperature protection „ Uses no electrolytic capacitors DESCRIPTION The NPH15S series of DC/DC converters combines ease of application with versatility. The pin pattern is based on the popular industry standard, but two additional pins may optionally be fitted to provide a variety of features not commonly found on units of this type. High efficiency enables full rating to be achieved in a small package without heatsinking, and a high surge capability will provide for start-up and transient loads, whilst being thermally protected against sustained overload. Overload protection of the “constant current” type ensures start-up into complex load conditions. The copper case achieves efficient heat transfer and screening. The product range has been recognised by Underwriters Laboratory (UL) to UL 1950 for operational insulation, file number E151252 applies.
