LD7592S 05/08/2018 Transition-Mode PFC Controller with Fault Condition Protection REV. 00 General Description The LD7592S is a voltage mode PFC controller operating on transition mode, with several integrated functions of protection, such as OVP, OCP, and brown-in protection. It reduces the components counts and is available in a SOP-8 or DIP-8 package. Those make it an ideal design for low cost applications. It provides functions of low startup current, over voltage protection, open feedback protection, disable function, over current protection, under voltage lockout and integrated LEB of current sensing. The LD7592S adopts transition mode for power factor correction and realizes high efficiency and a low switching noise by zero current switching.
