Introduction

AI Translation

LD8526U/UP 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, LD8526U/UP can be applied in CCM and DCM operation. In light load condition, LD8526U/UP will enter green mode to reduce operation current by stopping SR MOSFET driving function. LD8526U/UP can generate its own supply voltage through high side rectification applications to charge battery.

Features

AI Translation
  • 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 application, which output voltage range from 3V to 21V, and VCC range from 3V to 9V.
  • Programmable turn-off level
  • Fast turn-off total delay of 30ns
  • 200μA ultra-low green mode operation current
  • Gate source/sink capability: 0.5A/-3A

Applications

AI Translation
  • Switching AC/DC adaptor and battery charger
  • Open frame switching power supply
