Patent 9831767 was granted and assigned to Texas Instruments on November, 2017 by the United States Patent and Trademark Office.
A circuit and method for providing improved load transient response in a DC-DC converter. A DCM modulator is incorporated into the converter controller to generate a DCM enable signal for the driver circuits for the converter. During normal operation, the DCM enable signal will remain in a first state and the driver circuits will operate in a continuous conduction mode. However, upon a load transient, the DCM enable signal will change to a second state and the driver circuits will operate in a discontinuous conduction mode.
