Synchronous Rectification (SR) Driver with Green Mode Function
LD8520 is a secondary side synchronous rectification (SR) driver IC. With it's optimal dead time control method, switch mode power supplies can not only achieve high efficiency in dynamic load but also operation safety.
The IC 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.
The integrated load regulation improve function is an innovative step so that switch mode power supplies can achieve better laod regulation easily.
The IC is available in SMD. LD8520 GL in SOT-26 and LD8520 GS in SOP-8 package.
