Other Parts Discussed in Thread: PMP40766, UCC28180, , UCC256403, UCC256303
We want to use UCC256402 in the design of PMP40766. But since the starting voltage of UCC256402 is 26V. We were wondering if we could still ignore HV pin of it and turn it ON using Flyback converter? Please suggest a method to turn ON and maintain VCC supply for UCC256402 and UCC28180 in the same design.
