After discussing the three transistor high-side buck p-mosfet driver (a recognised circuit and not mine) with some of EW’s sage commenters, I wondered once again if I could design something similar ...
The switching speed of a power MOSFET charge-controlled device depends on the speed with which an associated gate driver circuit can charge its input capacitance. For the last 20 years, many excellent ...
With Linear Technology’s LT4320 ideal-diode bridge controller, power supply designers can replace each of the four diodes in a conventional full-wave bridge rectifier with a low-loss N-channel MOSFET.
Linear Technology Corporation is claiming a major breakthrough with the introduction of the LT4320, an ideal diode bridge controller for 9V to 72V systems that replaces each of the four diodes in a ...
There was this fellow, Rudy Severns, who many years ago went on a speaking tour for International Rectifier to discuss “Hexfets,” their power MOSFETs, when that product line was still new. If memory ...

Everyone loves a full-wave bridge rectifier, but there’s no denying that they aren’t 100% efficient due to the diode voltage drop. Which isn’t to say that with some effort we cannot create an ideal ...
The voltage across the capacitor pretending to be the mosfet gate capacitance is not getting close enough to the oV rail (see black rectangle below left) to turn off the mosfet properly – my ...
