Abstract
A switching power voltage regulator includes a pulse width modulation (PWM) signal generator, an output circuit and a feedback circuit. The PWM signal generator is configured to generate a PWM signal. The feedback circuit is configured to provide a feedback signal to the output circuit according to an output voltage of the output circuit. The output circuit includes an inductor, a plurality of inverters, and a driver. Each of the inverters includes a first transistor and a second transistor. When the inductor needs to be charged, the driver selectively switches one or more corresponding first transistors on according to the feedback signal.
