Abstract

A pulse-width modulation (PWM) controller to supply power to electronic components using a phase lock loop (PLL) is presented. A PWM controller comprises an input node operable to receive a reference signal and a phase-locked loop (PLL). The PLL comprises an oscillator operable to receive an error-correction signal and to generate an oscillator signal having a frequency that is related to the error-correction signal, a phase-frequency detector (PFD) coupled to the oscillator and operable to receive the reference signal and to generate the error-correction signal based upon a phase difference between the reference signal and a feedback signal, and a suppression circuit coupled to the PFD and operable to periodically enable the PFD to generate the error-correction signal.
