LD7592 - Leadtrend

LD7592 Transition-Mode PFC Controller

The LD7592 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.
