描述 Description

LD8520 is a secondary side Synchronous Rectification (SR) driver IC. With LD8520 Optimal Dead Time control method, switch power supply not only can achieve high efficiency in dynamic load but also operation safety.LD8520 is suited for Flyback low side and high side Synchronous Rectification in CCM and DCM. For Forward Freewheeling Rectification application, LD8520 can be applied in CCM and DCM operation.In light load condition, LD8520 will enter Green Mode to reduce operation current by stopping SR MOSFET driving function.Load Regulation Improve function is an innovative design in LD8520. With this unique function, switch power supply can achieve better Load Regulation easily.
