To manage and regulate power with both efficiency and finesse, electronics designers turn to Pulse Width Modulation (PWM).

A PWM circuit works by making a square wave with a variable on-to-off ratio; the average ‘on’ time may be varied from zero to 100%. In this manner, a variable amount of power is transferred to the ...

Hello,After reading a few post from stickmewithneedles and Unobtanium, I'm planning on making a thermal fan control circuit employing PWM. I've no EE degree, but I love electronics. Details(pdf ...

High-efficiency voltage conversion is maintained throughout the range of operating conditions by using PWM mode for normal- to high-current loads, then switching to LDO mode during very light loads to ...
