Abstract
A controller used in an isolated switching converter. The controller has an error amplifying circuit for generating a first compensation signal based on the difference between an output feedback signal and a reference voltage, a control generator for generating a first and second control signals based on the first compensation signal, an isolation circuit for providing a first synchronous signal electrically isolated from the first control signal and a second synchronous signal electrically isolated from the second control signal, an upper threshold generator for providing an upper threshold voltage, and a peak current generator for providing a peak current signal for controlling a peak value of a current flowing through the primary switch based on the first synchronous signal, the second synchronous signal and the upper threshold voltage. The upper threshold voltage is adjusted above a first upper threshold voltage when a peak power demand is made.
