RT7277是一款採用先進固定導通時間（ACOT™）模式控制的同步降壓型 DC/DC 轉換器。其實現了從 4.5V-18V 的輸入電源提供 3A 輸出電流的大功率密度。專有的 ACOT™ 模式能在大範圍的負載和所有種類的陶瓷電容間提供最佳的瞬態回應，使裝置採用非常低的等效串連電阻值輸出電容，以確保性能的穩定性。此外，RT7277 在線路和負載變化時會維持一個相當固定的切換頻率。可以進行 ACOT™ 模式操作的集成同步電源開關能在整個輸出電流負載範圍內提供高效率。逐週期電流限制可以根據低壓側金氧半場效電晶體的最小電流檢測提供精確的保護。外部軟啟動設置能在啟動期間消除輸入電流浪湧。保護功能還包括輸出欠壓保護、輸出過壓保護和熱關斷。
