摘要： A converting control circuit, adapted to control a converting circuit to convert an input voltage into an output voltage for driving a load, is provided. The converting control circuit comprises a current control circuit, a first detecting circuit, a second detecting circuit, a feedback controller and a feedback circuit. The current control circuit comprises at least one control end coupled to the load to adjust a current flowing through the load. The first detecting circuit is coupled to the current control circuit and generates a first detecting signal according to the voltage at the least one control end. The second detecting signal is coupled to the converting circuit and generates a second detecting signal according to the output voltage. The feedback circuit is coupled to the first and second detecting circuit and modulates a level of the second signal according to the first detecting signal.
