      SD8524H
      FAST TURN-OFF SYNCHRONOUS RECTIFIER CONTROLLER

          SD8524H is a high-performance, fast turn-off synchronous rectifier controller with a built-in 100V MOSFET. It replaces diode rectifiers for high efficiency in high-performance isolated power supply topology application. It can work with the flyback controller in CCM, DCM, QR modes.

          SD8524H can be powered by the high-voltage winding or the output voltage in the flyback converter applications. A slew rate detection circuit prevents the SD8524H from turning on falsely during resonance operation.

          The SD8524H is available in SOP8 package.


      Main feature

      • Integrated high-performance MOSFET (100V, 15mΩ)

      • Supports both high-side and low-side synchronous rectification applications

      • Supports DCM, CCM, and QR operations

      • Slew rate detection prevents false turn-on during resonance operation

      • Powered by the high-voltage winding or the output voltage

      • 250μA standby current

      • SOP8 package
