Abstract
Systems and methods for operating a switching converter are disclosed. The switching converter includes a high-side transistor coupled between a voltage input and a switching node and a low-side transistor coupled between the switching node and ground. The switching converter also includes a high-side driver coupled to drive a gate of the high-side transistor, a charge pump coupled to the high-side driver, and a bootstrap circuit, which includes a pass transistor coupled between the charge pump and the switching node, and a pull-down transistor coupled between the charge pump and ground.
