Beschreibung
Zusammenfassung:	A battery switching charger includes a PWM signal generator, a switching circuit, an inductor, a resistor and an analog-to-digital converter. The PWM signal generator is utilized for generating a PWM signal. The switching circuit includes cascoded transistors controlled by the PWM signal for generating an output voltage. The inductor is utilized for receiving the output voltage. The resistor is coupled between the inductor and a charge terminal of the battery switching charger, where the charge terminal is connected to a battery when the battery is being charged by the battery switching charger. The analog-to-digital converter is coupled to the PWM signal generator and the resistor, and is utilized for receiving voltages of two terminals of the resistor to generate control data to the PWM signal generator. In addition, the PWM signal generator adjusts a duty cycle of the PWM signal according to the control data.
