WebAlthough the bootstrap method has many advantages, it imposes significant limitations because of inherent charge time requirements. The capacitor can supply current to keep the high-sideMOSFET on for multiple switching cycles; however, once the charge is depleted, the circuit is forced to switch for a brief period of time to recharge the capacitor.
