Abstract
A digital regulator includes a voltage comparison circuit, a counter, a decoder and a switch circuit. At an initialization phase, the voltage comparison circuit is configured to compare the reference voltage signal and a first signal to output a first level signal, and the counter is configured to initialize and output an initialization signal as a control signal according to the first level signal. At an operation phase, the voltage comparison circuit is configured to compare the reference voltage signal and an output terminal of the switch circuit to output a second level signal, and the counter is configured to count according to the second level signal and output the control signal. The decoder is configured to turn on the plurality of switch units according to the control signal from the counter.
