Abstract
The present invention discloses a minimum on-time reduction method for a switching power conversion, comprising the steps of: generating a first reset signal and an over-supply pulse signal according to a current sensing signal and a reference signal; generating a blanking signal according to a count number of the over-supply pulse signal; and generating a second reset signal by performing Logic-AND operation on the first reset signal and the blanking signal. Furthermore, the present invention also provides a minimum on-time reduction apparatus for a power conversion, and a system using the minimum on-time reduction apparatus for a power conversion.
