A power switching voltage regulator includes a high-side switch, a low-side switch, an inductor, a detection circuit, and a gate voltage adjusting unit. The high-side switch is coupled to a voltage source; the low-side switch is coupled between the high-side switch and a ground. A connection node is located between the high-side switch and the low-side switch. The inductor is coupled between the connection node and a power output terminal of the power switching voltage regulator. The detection circuit detects an output voltage of the power output terminal, when the output voltage swings out of a predetermined range. The gate voltage adjusting unit dynamically adjusts a gate voltage on-resistances of the high-side switch and the low-side switch.

Power switching voltage regulator

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.
