Abstract
A method for controlling a voltage regulator is receiving a voltage identification code which has a pulse width modulation signal, providing a duty signal via measuring a duty cycle of the pulse width modulation signal, calculating a target voltage based on the duty signal, providing a reference signal via filtering the duty signal by a first filter if the voltage identification code varies, and providing the reference signal via filtering the duty signal by a second filter if the reference signal is in a range determined by the target voltage.
