集成了系統(tǒng)級保護的高能效、低功率、離線式開關(guān)電源IC

LinkSwitch-XT2在單片IC上集成了一個725 V / 900 V的功率MOSFET、振蕩器、簡單的開/關(guān)控制、一個高壓切換的電流源、頻率調(diào)制、逐周期限流以及熱關(guān)斷電路。啟動及工作時的功率直接來自于漏極引腳，無需使用偏置繞組及相關(guān)電路。 易于設(shè)計\r\n? 可選的器件限流點\r\n? 可選的自供電電路\r\n? 無論在PCB板上還是在封裝上都保證高壓的漏極引腳與其他所有引腳之間滿足高壓爬電要求\r\n? 輸出過壓保護(OVP)\r\n? 遲滯過熱保護(OTP)\r\n? 集成725 V額定電壓MOSFET，具有出色的抗浪涌性能\r\n? 元件數(shù)目極少，增加可靠性\r\n? 輕松滿足全球所有能效標準\r\n? 開/關(guān)控制可在極輕負載時具備恒定的效率，是達到強制性CEC標準的理想選擇;
