Offering high efficiency, typically up to 92%, the JWL and JSK series of regulated, metal cased 40 and 50W DC/DC converters has been announced by XP Power. Fitting the industry standard 50.8x25.4mm (2x1") footprint and pin outs, they are suited for use in a broad range of mobile and portable board mounted applications that require a high power density, up to 50W output and 1,500VDC input to output isolation.

The 40W JWL40 and 50W JWL50 both have two ultra-wide 4:1 input ranges offering 9-36 or 18-75VDC that cater for all popular nominal input voltages. The JWL40 features single or dual output models. Singles cover all popular output voltages in the range 3.3 to 24VDC and duals ±12 or ±15VDC. The JWL50 is a higher power single output version of the JWL40.

The JSK50 is a 50W single output device that has wide 2:1 input voltage ranges of 9-18, 18-36 and 36-75VDC. Like the JWL40/50 series output models cover most standard requirements in the range from 3.3 to 24VDC. The JWL50 and the JSK50 are equipped with a voltage trim function that allows adjustment of the output ±10% of nominal output in order to accommodate line losses or non-standard voltages.

All models can operate over the extended operating temperature range from -40 to + 105°C. An optional clip-on heatsink, specified when ordering (-HK), enables full power at an extended temperature range. Input to output isolation of 1,500VDC is standard across the range. A remote on/off input pin allows control and sequencing of the converter from host applications.

The JWL/JSK series is available from Farnell, element14, Digi-Key, approved regional distributors, or direct from XP Power and come with a three year warranty.
