Claim:
1. A circuit, comprising: a high-side power transistor having a source-drain path coupled between a first node and a second node; a low-side power transistor having a source-drain path coupled between the second node and a third node; a high-side drive circuit having an input configured to receive a drive signal and an output configured to drive a control terminal of said high-side power transistor, said high-side drive circuit including a capacitive driver comprising a first bootstrap capacitor having a first capacitor terminal coupled to said input of the high-side drive circuit and a second capacitor terminal coupled to the control terminal of said high-side power transistor; and a low-side drive circuit having an input configured to receive a complement drive signal and an output configured to drive a control terminal of said low-side power transistor, said low-side drive circuit including a level-shifting driver; and wherein said capacitive driver comprises:
