9 4 電路說明圖 4 中所示的電源供應器採用高壓降壓式結構的 LYT0006D (U1), 可在 38 VDC 輸出電壓下提供恆定的 135 ma 電流 該電源供應器專用於驅動 LED, 而 LED 應始終透過定電流 (CC) 驅動 4.1 輸入 EMI 濾波保險絲 F1 在異常狀況下提供電路保護 橋式整流器 BR1 提供全波整流 電容器 C1 和 C2 及差模電感器 L1 構成 π 濾波器, 以符合傳導性 EMI 標準 電阻器 R1 用於抑制輸入階段濾波器, 以實現良好的功率因數 (PF) 效能 電容器 C1 和 C2 還用於能量儲存, 以減少線間噪音並防止線電壓突波 4.2 LYTSwitch-0 LYTSwitch-0 已經過最佳化, 使得 LED 驅動器簡單易用 具有成本效益, 且在 0 至 100 C (LYTSwitch-0 殼體溫度 ) 內提供良好的線間電壓與溫度調節 PIXls 試算表用於平衡功率電感器和感測電阻器, 進而實現最佳線電壓調節 總輸入電容也有一定的效應, 但可透過調整感測電阻器 (R2 R3) 進行更正, 以最佳化效能 LYTSwitch-0 系列具有內建過熱限制, 可在燈泡承受過高溫度時保護電源供應器 降壓式轉換器階段由 LYT0006D (U1) 內的整合式功率 MOSFET 切換開關 飛輪二極體 (D1) 感測電阻器 (R2 R3) 功率電感器 L2 和輸出電容器 (C5) 組成 轉換器通常在 DCM 中運作, 以限制反向電流的週期 選用了快速飛輪二極體以將切換損失降至最低 4.3 輸出整流快速輸出二極體 (D1) 用於實現良好效率及降低溫度 通常在 LED 應用中, 外殼中的環境溫度高於 70 C 建議使用 t RR 較低 ( 小於 35 ns) 的輸出整流器, 因為低 t RR 可在二極體轉換至反向阻隔模式時將切換損失降至最低, 尤其是功率 MOSFET 中的切換損失 4.4 輸出回授透過跳離切換週期來維持調節 當輸出電流上升時, 流入 FB 接腳的電壓也會上升 如果此電壓超過 V FB, 則將跳離後續週期, 直到電壓降至低於 V FB 電流透過 R2-R3 進行感測並由 C4 進行濾波, 然後饋送至 FB 接腳進行精確調節 實現良好線間電壓調節的關鍵在於, 計算出最低電感後平衡功率電感器和感測電阻器的值 BYPASS 電容器 (C4) 連接回授接腳和源極接腳, 有助於降低輸出電流感測期間的功率損失 該電容器對饋送至 FB 接腳的回授電流資訊進行取樣與保持 FB 接腳與 C4 之間無需限制電阻器, 因為峰值電壓不會超過裝置接腳的最大輸入電壓額定值 Page 9 of 40
