描述：TOP243YN
TOPSwitch-GX 使用與 TOPSwitch 相同的經過驗證的拓撲結構，成本有效地集成高壓功率 MOSFET，PWM控制、故障保護等控制電路單個 CMOS 芯片。集成了許多新功能降低系統成本并提高設計靈活性、性能和能源效率。根據封裝類型，1 或 3 個額外的引腳TOPSwitch 標準 DRAIN、SOURCE 和 CONTROL端子允許以下功能：線路感應（OV/UV，線前饋/DCMAX降低），精確的外部設置電流限制、遠程開/關、與外部同步較低頻率和頻率選擇（132 kHz/66 kHz）。所有封裝類型都提供以下透明功能：軟啟動，132 kHz 開關頻率（自動降低輕負載時），頻率抖動降低 EMI，更寬的 DCMAX，滯后熱關斷和更大的爬電距離封裝。在此外，所有關鍵參數（即電流限制、頻率、PWM 增益）具有更嚴格的溫度和絕對容差以簡化設計并優化系統成本。


更低的系統成本，高度的設計靈活性
• 適用于更高功率應用的擴展功率范圍
• 無需使用 P/G 封裝的高達 34 W 的散熱器
• 功能消除或降低外部組件的成本
• 完全集成的軟啟動，可將應力/過沖降至最低
• 外部可編程的精確電流限制
• 更寬的占空比以獲得更大的功率、更小的輸入電容器
• Y/R/F 封裝上的獨立線路檢測和電流限制引腳
• 線路欠壓 (UV) 檢測：無關閉故障
• 線路過壓 (OV) 關斷擴展了線路浪涌限制
• 具有最大占空比 (DCMAX) 的線路前饋
減少抑制線路紋波并限制高壓線路的 DCMAX
• 頻率抖動降低了 EMI 和 EMI 濾波成本
• 無需虛擬負載即可調節至零負載
• 132 kHz 頻率減小了變壓器/電源尺寸
• Y/R/F 封裝中的半頻選項，用于視頻應用
• 用于自動故障恢復的滯后熱關斷
• 大熱滯后可防止 PC 板過熱

EcoSmart – 節能：TOP243YN
• 在遠程關閉模式下功耗極低
（110 VAC 時為 80 mW，230 VAC 時為 160 mW）
• 頻率隨負載降低，以實現高待機效率
• 允許通過 LAN/輸入端口關閉/喚醒
