產品詳情

說明

LinkZero-AX 是一款整合式離線切換 IC,可讓設計人員設計出零待機功耗的輔助電源供應器。LinkZero-AX 具備創新的斷電模式,能在終端產品處於閒置或待機時,有效地將輔助電源供應器關閉。斷電模式是透過一個可由微電腦存取的訊號觸發,這會完全關閉內部切換控制電路。不過,在斷電模式時,BP 接腳會保持穩壓狀態,讓 LinkZero-AX IC 可以透過重設脈衝或按一下按鈕喚醒。

與 CAPZero 和 SENZero 搭配使用時,LinkZero-AX 可使高功率產品的待機功耗降低至 5 mW,甚至到零。此外,LinkZero-AX 在斷電模式下,可以簡單的方式,於 4 V 時會從 BP 接腳提供高達 500 µA 電流。斷電模式下,當系統其餘部分處於待機時,這個電流可用來供電給系統的喚醒感測器。雖然這個功能會增加系統待機功耗,但是也可以提供一個簡單的方式來供電給低電流感測器,而不需要切換電源供應器。

產品特色

系統成本最低,待機功率為零

  • 簡單的系統配置提供零消耗的待機/斷電,由使用者控制喚醒
  • 極嚴格的 IC 參數公差可提高系統製造效率
  • 適用於低成本的 Clampless 設計
  • 頻率抖動功能可大幅降低 EMI 濾波器成本
  • 更大的封裝沿面距離可提高系統現場使用的可靠性

進階保護/安全功能

  • 磁滯回復過溫保護 - 自動恢復可降低現場退回率
  • 全輸入電壓範圍,全世界均可使用
  • 自動重新啟動功能可在發生短路及開迴路故障狀況下,將輸出功率降低達 85% 以上
  • 簡化開/關控制,不需迴路補償
  • 高頻寬可實現無過衝的快速啟動

EcoSmart - 節能

  • 230 VDC 輸入條件下,待機/斷電模式功耗低於 3 mW*
  • 無需新增元件即可輕易符合全球所有節能法規
  • 開/關控制可提供極輕負載的恆定效率

應用

  • 超低功耗的待機和輔助電源供應器

*IEC 62301 第 4.5 條將低於 5 mW 的待機功耗四捨五入為零。
