LD8526S - Leadtrend

LD8526S Synchronous Rectification Driver

LD8526S is a secondary side synchronous rectification (SR) driver IC. It is suited for flyback low side and high side synchronous rectification in CCM, DCM and QR mode. For forward freewheeling rectification application, LD8526S can be applied in CCM and DCM operation. LD8526S can generate its own supply voltage through high side rectification applications t.
