High-efficiency 40/50W DC-DC converters in compact standard packages

XP Power has introduced the JWL and JSK series of highly-efficient, typically up to 92%, regulated metal-cased 40/50W DC-DC converters. Offering a variety of input voltage range and single or dual output combinations, both series fit the industry standard 50.8mm x 25.4mm footprint and pin outs. With their compact dimensions they are ideal 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 the 50W JWL50 both have two ultra-wide 4:1 input ranges offering 9 - 36VDC 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 ± 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 wide 2:1 input voltage ranges of 9 - 18VDC, 18 - 36VDC 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 -40C to +10C. 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.
