摘要： A non-linear load driving circuit and a controller for controlling a conversion circuit to drive a non-linear load are provided. The controller includes a feedback unit, a pulse width control unit, and an overshoot reduction unit. The feedback unit generates a feedback signal according to a current feedback signal that represents a load current flowing through the non-linear load. The pulse width control unit generates a control signal according to the feedback signal to control a power output of the conversion circuit. The overshoot reduction unit generates an overshoot reduction signal when the load current changes from being smaller than to being greater than a predetermined value according to the current feedback signal. The pulse width control unit receives the overshoot reduction signal and reduces the duty cycle of the control signal accordingly. Thereby, stability of feedback control is improved and damage to circuit is prevented.

摘要： A power converting controller and an LED driving circuit are provided. The power converting controller controls a converting circuit, which converts an input power source into an appropriate power source to drive a load. The power converting controller includes a feedback control unit, an open-circuit judging unit and a protection unit. The feedback control unit controls the converting circuit according to a feedback signal representing the status of the load. As the open-circuit judging unit has judged that the load is continuously in an open-circuit status for a predetermined time length, the open-circuit judging unit generates an open-circuit protection signal. The protection unit is coupled to the feedback control unit and the open-circuit judging unit so as to generate a protection signal as receiving the open-circuit protection signal and thereby the feedback control unit enters a latch status to stop controlling the converting circuit.
