The LTC6101 amplifier is an example of a very good unidirectional, high-side current-sense amplifier. But that “unidirectional” is sometimes a problem. It means two things: you can't sense negative ...

Yesterday’s idea for a Cuk converter synchronous rectifier drive (right) seems to work, according to my use of LTspice. Yesterday’s idea for a Cuk converter synchronous rectifier drive (right) seems ...

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 ...

DC electronic loads have been available for electronic testing applications for several decades. Today’s products include switched resistors, high-speed active loads utilizing power semiconductors, ...

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 ...

Using a MOSFET as a switch is generally pretty simple. Make the gate voltage sufficient with respect to the source and current flows through the channel. However, if you are switching higher voltages, ...

The power transistor must be chosen to provide fast response while also withstanding high power dissipation. Several electrical and thermal characteristics must be considered: 1. An array of N current ...

Mission critical servers and communications equipment must continue to operate, even as circuit boards and cards are plugged-in or pulled-out for maintenance and capacity adjustment. Hot swap ...

Automotive incandescent bulbs have largely given way to more efficient, reliable, stylish, and even safer light emitting diodes (LEDs). LEDs turn on in a fraction of the time and are especially useful ...
