LD7591T Datasheet | Leadtrend Technology

Description The LD7591T 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 ponents 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, LD7591T is free from extra rectified AC line voltage information to minimize the power loss. The LD7591T will be disabled if INV pin voltage falls below 0.45V and the operating current rises over 65μA Features - Transition mode of PFC pre-regulator - Voltage mode control - Programmable max. on-time - Low Startup Current...
