Abstract
The present invention discloses an adaptive constant ON time adjustment circuit, which generates a square wave signal having a constant normal ON time during normal operation, for controlling a power stage circuit to convert an input voltage to an output voltage. When the output voltage is shifted from low to high, during the transient period, the ON time is adjusted longer; and when the output voltage is shifted from high to low, during the transient period, the ON time is adjusted shorter.
