Abstract

Disclosed is a power converter control circuit, comprising at least a power converter circuit and a control circuit. The power converter circuit is able to boost up an input voltage into a greater driving voltage and supply it to the driven device. Moreover, the power converter circuit is also able to generate a voltage signal and a current-sense signal separately, and then combine them into a joint voltage/current-sense signal. The control circuit receives the joint voltage/current-sense signal and resolves it into an over-voltage signal and a current-sense signal with the aid of a modulation signal. The two signals are separately fed into an over-voltage protection device and an over-current protection device for comparison; the outcomes are utilized to execute the over-voltage protection and the over-current protection.
