    Hello, I reviewed your schematic and noticed you are not using an RCD clamp. If you are not should try adding one. The application note you have gives instructions for setting this up. I also notice that you are not using a capacitor on the Vsense pin…

    You need connect all required components to UCC28630 to make it work. If you cannot see any pulses from its DRV after VDD reaches its on threshold, can you change a new UCC28630 to try? If you still cannot see DRV initial three pulses, power off your…
