Hi team,
How to calculate the required boot cap value? In datasheet, we recommend to use cap from 0.022uF to 0.1uF, but how to calculate in a given application?
Can boot cap > 0.1uF? Can boot cap < 0.022uF?
"High-side bootstrap supply. The bootstrap diode is on-chip but the external bootstrap capacitor is required. Connect positive side of the bootstrap capacitor to this pin. Typical range of HB bypass capacitor is 0.022 µF to 0.1 µF. The capacitor value is dependant on the gate charge of the highside MOSFET and must also be selected based on speed and ripple criteria."
