Dear,
This issue happened at only when start up and the first PWM of burst mode.
At these condition below, device work well:
-
Work in active clamp mode
-
After removed buffer IC
The gate signal can’t be measured due to high low side shorted while probe touched (GND is shortest loop)
But we can measure the gate signal before buffer IC, it’s normal.
Could you please advise that what signal we should measure for your reference, thank you.
Best regards,
Lawrence.
