The power stage includes an upper-gate switch, a first lower-gate switch and a second lower-gate switch. The first upper-gate switch is electrically connected between an input terminal and a switching node. The first lower-gate switch is connected in parallel with the second lower-gate switch, both of which are electrically connected between the switching node and a first node. The driver circuit controls the operation of the upper-gate switch and the first lower-gate switch. The bootstrap capacitor is electrically connected between a boot node and the switching node, wherein the boot node is electrically connected to a supply voltage. When a voltage across the bootstrap capacitor is smaller than a reference voltage, the second lower-gate switch is turned on to charge the bootstrap capacitor from the supply voltage."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Buck switching regulator","description":"The present invention discloses a buck switching regulator including a power stage, a driver circuit and a bootstrap capacitor.
