Both series fit the industry standard 50.8 x 25.4 mm footprint and pin outs for use in a broad range of mobile and portable board mounted applications that require a high power density, up to 50W output and 1,500 VDC input to output isolation.


The 40W JWL40 and the 50W JWL50 both have two 4:1 input ranges offering 9 – 36 VDC or 18 – 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 ± 12 VDC or ± 15 VDC. The JWL50 is a higher power single output version of the JWL40.


The JSK50 is a 50W single output device that has 2:1 input voltage ranges of 9 – 18 VDC, 18 – 36 VDC and 36 – 75 VDC. Like the JWL40/50 series output variations 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 + 105C. An optional clip-on heatsink enables full power at an extended temperature range. Input to output isolation of 1,500 VDC is standard across the range. A remote on/off input pin allows control and sequencing of the converter from host applications.
