CALCULATING THE BPN10 AND BP10V BYPASS CAPACITOR
The BPN10 capacitance provides energy for the high-side driver. The BPN10 capacitor should be a good quality,
high-frequency capacitor. The size of the bypass capacitor depends on the total gate charge of the high-side
MOSFET and the amount of droop allowed on the bypass capacitor. The BPN10 capacitance is described in
Equation 8.
