Abstract
A driving circuit includes: a first voltage dividing circuit arranged to generate a first voltage-divided signal according to a supply voltage; a second voltage dividing circuit arranged to generate a second voltage-divided signal according to specific voltage; a coupling circuit coupled between the first voltage dividing circuit and the second voltage dividing circuit, and arranged to couple the first voltage-divided signal into the second voltage-divided signal to generate a coupling signal; and a control circuit arranged to generate a control signal at least according to the coupling signal and a feedback signal to control a duty cycle of a transistor, wherein the feedback is generated by the transistor.
