V Minthe application note states this is the minimum voltage between the Vb and Vs.
Should I use applicatioh 1uF cap. Yes, my password is: Do you already have an account? Jun 30, For what its worth, by assuming that I can ignore capacitor leakage current and Vmin, I used the above expression and the values I found for a frequency of 50Hz.

Does the capacitor need to be bigger than this in practice? Pspice Simulation with IR Hope I could help.
I just redid my calculation and the answer turns out to be the same. The application note is clear on ceramic vs. I cbs – leakBootstrap cap.

Unfortunately, by looking at the suggested schematic see below I’m unable to understand what value should I be using for this. If it does then cross conduction is highly likely.

Try also the other mosfet. Is there a drawback to having a large bootstrap capacitor? Posted by Runs in forum: I R 2 3 04 switch frequency: The value for 20kHz is 0.
