LD8523P

LD8523/P 11/24/2017 Synchronous Rectification Driver with Green Mode Function REV. 00 General Description LD8523/P is a secondary side synchronous rectification (SR) driver IC. It combines a low voltage drop N-channel MOSFET to improve efficiency and reduce heat from secondary-side rectifier. LD8523/P is suited for flyback low side and high side synchronous rectification in CCM, DCM and QR mode. For forward freewheeling rectification application, LD8523/P can be applied in CCM and DCM operation. In light load condition, LD8523/P will enter green mode to reduce operation current by stopping SR MOSFET driving function. Load regulation improve function is an innovative design in LD8523/P. With this unique function, switch power supply can achieve minimum load regulation easily.
