Other Parts Discussed in Thread: UCC28780
I'm a student who is studying by purchasing the UCC28780 EVM-002.
I'm studying the design of active flyback converter using UCC28780 by referring to the EVM.
I plan to use another GaN(Gansys, GS-065-011) and Gate Driver(output UVLO 3V) and voltage regulator.
The Problem is
1. After the RUN voltage is set, the PWML signal becomes High after 2.2us.
2. At this time, the voltage regulator used in the Gate driver does not form 3V within the time.
Can you tell me if there is a specification of the voltage regulator or Gate Driver recommended for this?
