摘要： A power-good signal generator generates a power-good signal according to a control signal of a controller, and comprises an impedance element, a controlled transistor and a power sequencing free circuit. An end of the impedance element is coupled to a second voltage source. The controlled transistor has first and second input/output ends and a controlled end, wherein the first input/output end is coupled to the other end of the impedance element to generate the power-good signal. An operating state of the controlled transistor is changed in response to the control signal. The power sequencing free circuit is coupled to the controlled end and one of the first input/output end and the second voltage source. When the second voltage source is supplied before the first voltage source, the power sequencing free circuit turns on the controlled transistor to clamp the power-good signal to be lower than a predetermined voltage level.

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.
