Other Parts Discussed in Thread: TIDA-00779,
Hello,
In TIDA-00779, is the PFC ON pin an input pin or an output pin? Also, please explain how the shutdown circuit functions. Is the switch S1 used to remove power supply from UCC28180? If yes, how does it work?
Also, in the J3 connector, is the AC Sense connected only for testing purpose? Does it have any function other than use in boost follower circuit?
