LD8926AA1 - Synchronous Rectification Driver

Description

LD8926AA1 is a secondary side synchronous rectification (SR) IC with drive element and MOSFET.

It is suited for flyback low side and high side synchronous rectification in CCM, DCM and QR mode.

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.

LD8926AA1 06/14/2019 Synchronous Rectification Driver with Green Mode Function REV. 00 General Description LD8926AA1 is a secondary side synchronous rectification (SR) IC with drive element and MOSFET. It is suited for flyback low side and high side synchronous rectification in CCM, DCM and QR mode. In light load condition, LD8926AA1 will enter green mode to reduce operation current by stopping SR MOSFET driving function. LD8926AA1 can generate its own supply voltage through low output voltage or high side rectification applications to charge battery. To reduce assembly process, layout area, and production cost, SR MOSFET and LD8926AA1 control core are packaged in SOP-8.
