Why use a BJT in a flyback converter?

In many low-power applications such as USB adaptors, cell phone chargers, and system bias supplies, the low-cost quasi-resonant/discontinuous-mode flyback converter ...

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 ...

Test Setup Checks Transistors’ hFEs When Tight Control Is Important

This file type includes high resolution graphics and schematics. The spread of h FE values in a batch of transistors may be wide enough to cause unreliable performance during mass production of a ...
