Abstract
A controller used in an isolated switching converter having a transformer and a primary switch. The controller has an error amplifying circuit, a control generator, an isolation circuit and a threshold generator. The error amplifying circuit generates a first compensation signal based on the difference between an output feedback signal and a reference voltage. The control generator generates a first and second control signals based on the first compensation signal. The isolation circuit provides a first synchronous signal electrically isolated from the first control signal. The threshold generator generates a current threshold voltage for controlling a maximum current flowing through the primary switch. The current threshold voltage gradually increases during a start-up period, and is generated based on the first synchronous signal after the start-up period.
