  • GaN FETs Give DC-DC Converters Big Improvements

    I've recently designed a 650 Watt DC-DC Buck Converter for a satellite and I chose to use GaN FETs for both the series switch and for the synchronous rectifier. For this power range, I could not believe how small these new generation 5, chip-scale GaN…

  • Isolated DC-DC converters in series

    Hello everyone, I am using two wireless charging modules for powering my circuit. The receiver part has 5v DC DC buck converter and I would like to connect the output of two modules in series to form a +/- 5v dual supply. Is there any chance of damaging…
