MrHeckles Posted May 4, 2006 Report Share Posted May 4, 2006 One simple question about the SG3524 regulating PWM chip.The error amp inputs are pins 1 and 2, the output of the error amp (and the compensation) pin is pin 3. The current limit amp inputs are 4 and 5.The current limit amp will over ride the output of the error amp.My question is, if I was to drive the voltage on pin 3 directly, would the output of the current limit amp over ride it to drop the duty cycle in the event of an over current detection?
