Latest Patents
One of Yi-Cheng Wan's latest patents is a control circuit and method for providing a signal for a PWM voltage regulator to convert an input voltage into an output voltage. This invention combines a high-frequency feedback technique with a constant on-time or constant off-time topology to improve the transient performance of the PWM voltage regulator. The regulator generates a constant on-time or off-time based on the current for producing a PWM signal, dynamically adjusting the current according to the droop voltage at its output during transient periods. This innovation enhances the transient response of the PWM voltage regulator without requiring a threshold for load step detection.
Another notable patent is for a multi-phase switching regulator and droop circuit. This invention provides a multi-phase switching regulator that generates PWM signals based on an output voltage and a droop signal. The droop circuit detects the sum of the currents produced by multiple switching sets and provides a droop signal related to this sum. This droop signal can be utilized for overcurrent protection or droop control, further improving the efficiency and reliability of voltage regulation systems.
