mosfet – Bootstrap Capacitor Selection with IR/3 – Electrical Engineering Stack Exchange
One question though – suppose I require a capacitor of 1uF. From the application notethe expression to find the bootstrap capacitor is as follows. I just redid my calculation and the answer turns out to be the same. Could you ie2113 me how much power you are using as your load?

Try also the other mosfet. Maybe you can try to turn 1 mosfet gate off first. I have a boot strap circuit and have also charged the capacitor by giving pulse to low side switch first.
Jul 3, I cbs – leakBootstrap cap. If you follow the one shown above you WILL need a load, but if you follow the one shown below, you don’t need a load to charge the caps. I just redid my calculation and the answer turns out to be the same. The value for 20kHz is 0.
