> 產品介紹 > JP8020系列晶片

JP8020 是集成了離線AC / DC控制器,具有集成的高壓GaN晶體管,可實現高性能操作。


JP8020使用基於光隔離器的反饋來針對傳統反激式架構。 它可以使用傳統的系統架構,在高達500 kHz的頻率下工作,以改善變壓器尺寸和功率密度。

JP8020實現了啟動控制器和脈衝隔離接口,以實現外部原邊或副邊控制。 使用次級側控制器可以改善瞬態響應並管理負載接口。


JP8020 Features

  • Integrated 290 mΩ  or 125mΩ GaN transistor
  • Integrated startup regulator    
  • Operation up to 500 kHz
  • Brown-in/out
  • OVP for secondary side
  • Valley-switched operation for high efficiency
  • Minimal BOM count and cost
  • Low standby power
  • 5mm x 6mm QFN package


JP8020 Applications

  • USB type-C power adapters
  • Cell-phone and tablet chargers
  • Laptop adapters
  • Consumer electronics
