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
