摘要： A level-switching device is coupled to an output node of a PWM converter to switch the output voltage of the PWM converter between two levels by switching a MOS. An undershoot/overshoot eliminator is coupled to the MOS for the MOS changing from totally on state to totally off state or vice versa softly when switching the MOS. The feedback signal transition in the level-switching device becomes slower when switching the MOS to eliminate overshoot/undershoot on the output voltage.
