| 主权项 | 1. A method of regulating voltage by a voltage regulator including a digital controller, the method comprising: calculating a first PFM on time based on an input voltage of the voltage regulator and an output voltage of the voltage regulator; calculating a second PFM on time different than the first PFM on time based on the input voltage and the output voltage, at least one of the first and second PFM on times being further based on a period of a main clock for the digital controller; selecting only one of the first PFM on time and the second PFM on time according to a selection criteria; and activating and deactivating at least one switch according to the selected PFM on time. | ||
