While lacking the glitz of so-called digitally-based systems (search www.eeProductCenter.com for article ID:163105176), traditional PWM-based controller ICs for today’s switching power supplies show a ...

A few weeks ago, I saw a reader’s question about how to run PS3 cooling fans using an external electronics circuit. At the time I was busy with some other projects. The other day, I decided to put my ...

The ISL6545 and ISL6545A from Intersil are single-output PWM controllers. These devices integrate the MOSFET drivers, boot diode and current-sensing functions on a single chip. The ISL6545 and ...

iWatt has launched two digital pulse width modulation (PWM) controllers that enable smaller (as small as 2cm x 2cm x 1.7cm), greener power adapters up to 40W. iWatt has launched two digital pulse ...

However, not all innovations are equal and nor do they follow a constant upward trend. Instead, their evolution takes the form of an S-shaped curve that reflects their typical lifecycle from early ...

Pulse Width Modulation (PWM) is a fundamental technique in power electronics that facilitates the efficient control of power delivery by modulating the width of voltage or current pulses. This method ...

Normal fan ports are only 1 amp, so I don't typically like running more than one fan per. That's only 5 watts, after all. Normal fan ports are 12V, not 5V. A lot of 12V fans won't even start at 5V, ...
