40- and 50-Watt DC-DCs in 2 x 1 Inch Footprint
XP Power has announced the JWL and JSK series of regulated, highly-efficient, typically up to 92%, metal cased 40- and 50-Watt dc-dc converters. Offering a variety of input voltage range and single- or dual-output combinations, both series fit the industry standard 50.8 x 25.4 mm footprint and pin outs. With their compact dimensions they are designed for use in a broad range of mobile and portable board mounted applications that require a high power density, up to 50 Watts output and 1,500Vdc input to output isolation.
The 40-Watt JWL40 and the 50-Watt JWL50 both have two 4:1 input ranges offering 9- to 36-Vdc or 18- to 75-Vdc 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 24-Vdc, and duals ±12Vdc or ±15Vdc. The JWL50 is a higher power single output version of the JWL40.
The JSK50 is a 50-Watt single-output device that has 2:1 input voltage ranges of 9- to 18-Vdc, 18- to 36- Vdc and 36- to 75-Vdc. Like the JWL40/50 series output models cover most standard requirements in the range from 3.3- to 24-Vdc. 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 degrees 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 3 year warranty.
