A New Approach to Circuit Breaker Design Using Silicon Carbide Switches - Nov 21
Mechanical circuit breakers can be low cost with minimal losses, but they operate slowly and wear out. Solid state versions overcome the problems and are becoming increasing viable as replacements at...

Efficient 40/50W DC/DC converter series is compact
The metal cased DC/DC converters offer a variety of input voltage range and single or dual output combinations. Both series fit the industry standard 50.8 x 25.4mm footprint and pin-outs. The compact dimensions make them suitable for a range of mobile and portable board mounted applications that require a high power density, up to 50W output and 1,500V DC input to output isolation.

The converters have wide 4:1 input ranges offering 9 to 36V DC or 18 to 75V DC catering 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 24V DC, and duals ±12 or ±15V DC. The JWL50 is the higher power single output version.

The JSK50 is a 50W single output device that has wide 2:1 input voltage ranges of 9 to 18V DC, 18 to 36V DC and 36 to 75V DC. All models cover most standard requirements in the range from 3.3 to 24V DC.

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 enables full power at an extended temperature range­­­. Input to output isolation of 1,500V DC is standard across the range. A remote on/off input pin allows control and sequencing of the converter from host applications.
