Abstract
A system and a method for improving continuous load transition of a DC-DC converter are provided. The system includes a conduction detector circuit, a counter circuit, a depth control circuit and a slope generator. The conduction detector circuit detects a phase signal of the DC-DC converter to generate a pulse signal. The counter circuit counts the number of pulse waves of the pulse signal to output a counting signal. The depth control circuit generates a pulled-down depth signal. The slope generator generates a slope signal according to the pulled-down depth signal. The pulled-down depth signal is pulled down by a first depth each time the switch circuit is conducted, but when the number of times that the switching circuit is conducted reaches a conduction number threshold, the pulled-down depth signal is pulled down by a second depth that is larger than the first depth.
