POWER SUPPLY SYSTEMS AND METHODS

摘要

Aspects include a power supply system. The system includes an oscillator system configured to generate a clock signal at a clock node. The oscillator system includes a comparator configured to compare a first variable voltage at a first comparator node and a second variable voltage at a second comparator node. The first and second variable voltages can have respective magnitudes that are based on a state of the clock signal. The system also includes a pulse-width modulation (PWM) generator configured to generate a PWM signal based on an error voltage and the clock signal. The system further includes a power stage configured to generate an output voltage based on the PWM signal.
