Power Integrations 針對主要家電製品應用提供一系列高度整合的離線式功率轉換用高電壓 IC。單一晶片中,每個 IC 包含結合控制與保護電路的 ≥700 V 功率的 MOSFET。其功能包括電流限制、具備自動故障復原能力以增進可靠度的過熱關機保護、降低 EMI 的頻率抖動及可明顯降低待機能源消耗的 EcoSmart 技術。

偏高及不穩定電源電壓

高品質電器和其他消費性電子產品在主電源電網不穩定的地區、頻繁發生雷擊的熱帶區域或高能量振盪波和突波非常普遍的任何區域使用時,需要有較高的電壓餘裕。例如,在印度迅速發展的高品質消費性產品市場中,產品若沒有該餘裕,OEM 就必須要處理源源不斷的電子損壞和退貨產品,而這些產品需要維修或更換。

Power Integrations 擁有一系列整合了 900 V 一次側 MOSFET 的完整離線式切換開關 IC,可提供有效且低成本的防護,並且運作和產品支援成本大幅減少。

  • LinkSwitch-TN2 適用元件數極少的降壓轉換器
  • LinkSwitch-XT2 適用高達 8 W 隔離或非隔離反馳式轉換器
  • InnoSwitch3-EP 適用高達 85 W 高功率隔離反馳式轉換器

這些高度整合的 900 V 裝置讓設計工程師能夠實現真正的「一體式」電源供應器,可滿足任何地方使用者的可靠性預期。上述裝置可取代現有電路板設計中對應的 725 V 切換開關,以便在不更改設計的情況下也能支援較高的電壓。

InnoSwitch3-EP系列的新添加產品採用了900 V的氮化鎵(GaN)技術,能夠提供最高100 W的功率,效率超過93%,並在空間受限的應用中消除了散熱片的需求。PI的專有PowiGaN技術提供了實現900 V額定值所需的可靠性和堅固性,同時增加了功率和效率,為電壓高或不穩定的地區提供了更寬的安全邊際。
