Having a big block of hot to dump current into is a very useful thing to have if you’re testing batteries, power supplies, high power LEDs, electroplating, or any thing else that would normally ...

If you ever work with a circuit that controls a decent amount of current, you will often encounter a FET – a Field-Effect Transistor. Whether you want to control a couple of powerful LEDs, switch a ...

In Part 1 of this five-part series, we examined FET voltage controlled resistors, basic voltage controlled resistor circuits, and a balanced or push pull voltage controlled resistor (VCR) circuit.

If you are going to use a silicon carbide (SiC) MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) in your next development, you will ask yourself: how do I develop the best gate driver for it ...

Having thought up and simulated a drive circuit for the synchronous rectifier in a Cuk converter, I thought I would wrap it all up by appling the things I learned to the original circuit – a high-side ...

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 ...

How is peak current defined? A close look at datasheet headlines and how they vary. A case study that compares different drivers and peak currents. One question often comes up when considering what ...
