Abstract
In an example, a system comprises a boost power factor correction (PFC) converter that includes a thermistor, an inductor, and a transistor and a PFC controller coupled to a common node. The PFC controller includes a comparator coupled to a threshold voltage source and to a terminal of the transistor. A first flip-flop is coupled to the comparator and to a control terminal of the transistor. A zero current detector is coupled to the inductor. A timer is coupled to the comparator and to the zero current detector. A second flip-flop is coupled to the timer and to the control terminal of the transistor. An AND gate is coupled to the first and second flip-flops. The circuit includes third and fourth flip flops.
