LD8526 - Synchronous Rectification Driver

General Description

LD8526 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, LD8526 can be applied in CCM and DCM operation.

Key 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 primary side with peak load function (max. frequency 130kHz).
  • Suited for PD.

Synchronous Rectification Driver with Green Mode Function LD8526 08/31/2018 REV. 00 General Description LD8526 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, LD8526 can be applied in CCM and DCM operation. In light load condition, LD8526 will enter green mode to reduce operation current by stopping SR MOSFET driving function. LD8526 can generate its own supply voltage through low output voltage or high side rectification applications to charge battery.
