LD8526S - Synchronous Rectification Driver

Datasheet Summary

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.

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 Applica.

Synchronous Rectification Driver LD8526S 01/03/2020 REV. 00 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.
