Abstract

A switching charger having fast dynamic response for transition of a load is provided. A first terminal of a high-side switch is coupled to an input voltage. A first terminal of a low-side switch is connected to a second terminal of the high-side switch. A first terminal of an inductor is connected to a node between the first terminal of the low-side switch and the second terminal of the high-side switch. A second terminal of the inductor is connected to a first terminal of a capacitor. A constant on-time circuit determines a duty cycle of an on-time signal according to the input voltage and an output voltage of a node between the second terminal of the inductor and the first terminal of the capacitor. A control circuit controls a driver circuit to drive the high-side switch and the low-side switch according to the on-time signal.
