Hello,
I simulated an IR2110 on LTSpice on a 1k load with only high side drive.
PWM config :
rise time = 1.75u
fall time = 1.75u
on time = 40u
period time = 50u
(it's 20khz with high duty cycle)
Weird results with voltage dropping on gate:
If I reduce the bootstrap capacitor or the load, it works fine, looks like bootstrap charging or discharging from the load ?
Is that normal ?
