发明名称 System and Method for a Switch Driver
摘要 In accordance with an embodiment, switch driver includes a first switch driver configured to be coupled to a control node of a first switch, a second driver configured to be coupled to a control node of a second switch, and a first terminal and a second terminal configured to be couple to a boot capacitor. The first terminal is coupled between a boot input of the first switch driver and the second terminal is configured to be coupled to outputs of the first switch and the second switch. The switch driver further includes a voltage measurement circuit coupled to the first terminal and the second terminal, and a control circuit configured to activate the second switch driver when the voltage measurement circuit indicates that a voltage across boot capacitor is below a first threshold.
