General Description
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 to charge battery.

Features
 Suited for low side and high side flyback synchronous
rectification in CCM, DCM and QR(valley lock) mode
 Suited for forward freewheeling rectification in CCM
and DCM
 Self-supplying for operation with low output voltage
and/or high–side rectification without an auxiliary
winding.
 Suited for PSR with peak load function (max. frequency
130kHz)
 Programmable turn-off level
 Fast turn-off total delay of 30ns
 Gate source/sink capability: 0.5A/-3A

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