LD7591S规格书详情

描述 Description

The LD7591S is a voltage mode PFC controller operating in 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.Unlike the traditional current mode PFC controller, LD7591S is free from extra rectified AC line voltage information to minimize the power loss.The LD7591S will be disabled if INV pin voltage falls below 0.45V and the operating current rises over 65μA
