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.
