In this power tip, I’d like to present two approaches that both reduce design complexity and noise coupling in isolated bias supplies. One approach, useful for multiple isolated outputs and overall ...

Compared with the traditional isolated power supply chip, this new design interconnects the receiving and transmitting chips through the micro transformer made of the rewiring layer, ...

How switch-mode power supplies changed the power-supply design space. The isolation factor in power supplies: galvanic isolation vs. non-isolated. Most common non-isolated topologies. This series ...

In isolated power supplies, optocouplers pass the feedback signal across the isolation boundary. Optocouplers contain both a light-emitting diode (LED) and a photo detector. Current flowing through ...

Allegro MicroSystems has launched an isolated gate driver – the first product in the company’s Power-Thru portfolio – which is a single-package solution that drives GaN FETs. A traditional gate driver ...

For the gate drivers of high-power IGBTs, mosfets, SiC mosfets and GaN hemts, Infineon has introduced an isolated power supply IC that can generate asymmetric output voltage rails. Each member of the ...
