Woodward notes a PWM nonlinearity in a DI that software can't fix, and presents a potential solution: adjusting resistor ...

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 ...

In a previous article, I discussed LEDs in general and their properties. In this write-up, I want to give some examples of driving LEDs and comparing a few of the most commonly used methods. There is ...

Linear Technology Corporation announces the LT3753, a primary side, current-mode PWM controller optimized for use in a synchronous forward converter with active clamp reset. Linear Technology ...

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, ...

Linear Technology Corp.’s new LTC3723 push-pull synchronous PWM controller is specifically targeted toward compact and highly efficient isolated power Linear Technology Corp.’s new LTC3723 push-pull ...

A cooling system can sometimes be a buzzkill. You drop your badass engine into your badass hot rod, and then you remember you've got to keep it cool. As an afterthought, you order a big aluminum ...
