The current requirements are rather minor, so this type of DC-DC converter is all that is needed. You start from a low-impedance AC/switching signal (in a bootstrap this would be the output node of the driver).
WebNov 13, 2024 · Bootstrap Circuit. The bootstrap power supply is one of the most widely used methods to supply power to the high-side drive circuitry of a gate driver IC. It consists of a bootstrap diode and a bootstrap capacitor as shown in the following figure. This method has the advantage of being both simple and low-cost. WebMOSFET properly, a bootstrap circuit is designed to generate a floating power supply between gate node and source node of the MOSFET and an external small ceramic capacitor between the BOOT and PH pins is required. This bootstrap capacitor is refreshed when the HS MOSFET is off and the catch diode or low-side (LS) MOSFET conducts.
