Abstract
A Buck converter includes: a first power switch coupled between a supply voltage node and a switching node, where the first power switch is configure to be controlled by a first control signal; a boot-strap capacitor, where a first terminal of the boot-strap capacitor is coupled to the switching node; a first buffer coupled between a first node and a control terminal of the first power switch; a first switch circuit coupled between the first node and a second terminal of the boot-strap capacitor, where the first switch circuit is controlled by the first control signal, and is configured to pass through a first charging current provided by the boot-strap capacitor when the first control signal is asserted; and a slew-rate control capacitor, where a first terminal of the slew-rate control capacitor is coupled to the first node.
