Hello,<P>After reading a few post from <B>stickmewithneedles</B> and <B>Unobtanium</B>, I'm planning on making a thermal fan control circuit employing PWM. <P>I've no EE degree, but I love electronics ...

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 ...

Phoenix, Ariz. — The NCP1501 alternates from a PWM buck converter to an LDO regulator to deliver 92 percent power efficiency at heavy current loads and reduce noise and quiescent current at light ...
