Abstract:
A driver circuit includes a high-side power transistor having a source-drain path coupled between a first node and a second node and 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, includes an output configured to drive a control terminal of said high-side power transistor. The high-side drive circuit is configured to operate as a capacitive driver. A low-side drive circuit, having an input configured to receive a complement drive signal, includes an output configured to drive a control terminal of said low-side power transistor. The low-side drive circuit is configured to operate as a level-shifting driver.
