Overview
Synchronous Rectification Driver with Green Mode Function LD8521 07/28/2016 REV.
00 General Description LD8521 is a secondary side Synchronous Rectification (SR) driver IC.
With LD8521 Optimal Dead Time control method, switch power supply not only can achieve high efficiency in dynamic load but also operation safety.
LD8521 is suited for Flyback low side and high side Synchronous Rectification in QR (quasi-resonance) mode.
In light load condition, LD8521 will enter Green Mode to reduce operation current by stopping SR MOSFET driving function.
Load Regulation Improve function is an innovative design in LD8521.
With this unique function, switch power supply can achieve better Load Regulation...
