Abstract

See full text

A current limit peak regulation circuit, a current limit circuit and a power converter including the current limit peak regulation circuit. The current limit peak regulation circuit provides a current limit threshold to limit a maximum allowable peak current value of a current flowing through a main switch of the power converter and adjusts the current limit threshold to decrease with decrease in a switching frequency of the power converter when the power converter is in a constant voltage mode so as to reduce power dissipation of the power converter in standby mode.
