Hi Tan, did you get the issue fixed? What was the critical solution, freewheeling, snubber, or ? I ran into the exact same issue. Having a through-hole prototype board, my biggest concern is relatively long wires and plenty of stray inductance/capacitance. Although I am operating at Hz level (hence no gate-source bleed resistor used as my boost refresh rate is very low), not kHz or MHz, could the fast transition at the gate drive be the source of all evil (driving large 1nF gate capacitance)? Thanks for sharing additional insight! - Bert
