Tl494 boost converter circuit
WebMay 9, 2024 · The TL494 is backwards in every way. --Most PWM turn on by the clock and turn of at a duty cycle. The 494 turns off at the clock time. --Most PWM, the feed back goes to the (-) input of a error amplifier. The 494 used (+) input. Non inverting gain that can not go below a gain of one. Making a stable error amp harder. http://www.stevehv.4hv.org/boost_converter.htm
