LD8926AA1 Synchronous Rectification Driver

LD8926AA1 is a secondary side synchronous rectification (SR) IC with drive element and MOSFET. It is suited for flyback low side and high side synchronous rectification in CCM, DCM and QR mode. In light load condition, LD8926AA1 will enter green mode to reduce operation current by stopping SR MOSFET driving function. LD8926AA1 can generate its own supply vol.
