Whether it is a forward, buck, boost or a flyback topology, the current-mode controller will require monitoring of both loops for standard operation. Historically, in contrast to current-mode control, the older WebShutdown of the UC3842 can be accomplished by two methods; either raise pin 3 above 1V or pull pin 1 below a voltage two diode drops above ground. Either method causes the output of the PWM comparator to be high (refer to block diagram). The PWM latch is reset dominant so that the output will remain low until the next clock cycle after the ...
