Synchronous Rectification (SR) Driver
LD8526S is a secondary side synchronous rectification (SR) driver IC.
The IC 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.
In light load condition, LD8526S can generate its own supply voltage through low output voltage or high side rectification applications to charge batteries.
The IC is available in SMD. LD8526S GL in SOT-26 package.
