Abstract
A current threshold regulation method is used in a switching converter with a tank element and a transistor. The current threshold regulation method includes: detecting whether the input voltage is lower than an input under voltage threshold and generating an input under voltage indication signal; detecting whether the output voltage is lower than an output under voltage threshold and generating an output under voltage indication signal; generating a current threshold based on the input under voltage indication signal and output under voltage indication signal; comparing a current flowing though the tank element with the current threshold and generating a current comparison signal; and generating a control signal based on the current comparison signal to control the transistor.
