Overview

LD8526U/UP 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, LD8526U/UP can be applied in CCM and DCM operation. In light load condition, LD8526U/UP will enter green mode to reduce operation current by stopping SR MOSFET driving function. LD8526U/UP can generate its own supply voltage through high side rectification applications to charge battery.

Applications

Switching AC/DC adaptor and battery charger
Open frame switching power supply
