A solar charge controller is a device found in a photovoltaic (PV) energy system that controls the amount of power that can be transmitted to an electric storage battery. By controlling the charge ...

Modern power delivery systems with DSPs, FPGAs and CPUs run on lower supply voltages and consume higher current. In fact, sub-1 V voltages are everywhere now. Meanwhile, intermediate bus voltages have ...

The new UCC28220 and UCC28221 from Texas Instruments (TI) is the industry's first single-chip, interleaved pulse-width modulation (PWM) controllers for The new UCC28220 and UCC28221 from Texas ...

For the PDF version of this article, click here. Over the years, power supply designers have been persuaded that current mode is superior to its voltage-mode counterpart. As a result, the major PWM ...

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 ...
