DC-DC CONVERTER CONTROLLER HAVING OPTIMIZED LOAD TRANSIENT RESPONSE AND METHOD THEREOF

摘要

A power supply controller (25) is configured to accurately adjust the value of an output voltage of a power supply system (10) responsively to the output voltage increasing to an undesirable value. The controller (25) accurately limits an upper value of the output voltage during a light load condition, and rapidly reduces the value of the output voltage during a light load condition, and different control signals to control the switching of the output transistors facilitates rapidly reducing the output voltage.
