Off-line flyback uses HV transistor in common-base configuration

OK, so I get a press release (pdf) from those wonderful folks at CamSemi, AKA Cambridge Semiconductor. It talks about their C2163 off-line switcher chip (pdf). The press release says: “…the BOM cost ...

Beginner Concepts: MOSFETs

[Moser’s] introductory guide to MOSFETs serves as a quick introduction for those unfamiliar with the parts. They fill a similar role as a bipolar junction transistor like the 2N2222, making it ...
