MULTIPLE POWER SUPPLY SYSTEMS AND METHODS

摘要

Aspects of the present invention include a power supply system comprising a plurality of power supplies. Each of the power supplies can include an oscillator system configured to generate a clock signal at a clock node. Each of the power supplies can include an error amplifier configured to generate an error voltage at an error amplifier output node. Each of the power supplies can also include a pulse-width modulation (PWM) generator configured to generate a PWM switching signal based on an error voltage and the clock signal. Each of the power supplies can further include a power stage configured to generate an output voltage based on the PWM switching signal.
