LD8530Dual LLC Synchronous Rectifier Driver with Green Mode Function

LD8530 is a dual channel secondary side synchronous rectification (SR) driver IC. It is suited for LLC resonant converters synchronous rectification in CCM and DCM mode.
In light load condition, LD8530 will enter green mode to reduce operation current by stopping SR MOSFET driving function.

 

 

Features

  • Suited for LLC resonant converters in CCM and DCM mode
  • Suited for primary side with peak load function (max. frequency 600kHz)
  • 3.9V to 65V Wide VCC Operating Range
  • Dual-channels interlock circuit to avoid shoot-through
  • Adaptive TMIN_OFF switching
  • Adjustable green mode timing
  • 23ns fast turn off propagation delay
  • LDO for avoiding short circuit at AC on
  • 200mA ultra-low green mode operation current
  • Gate source/sink capability: 0.3A/-3A

 

Applications

  • Switching AC/DC adaptor
  • Desktop PC, AIO PC, ATX and server power
