RT8511A 是可以驅動多達10只串聯連接的 WLED 的驅動 IC , 內部包含一個集成了 43V/1.2A 功率開關的電流模式 Boost 轉換器，工作頻率為固定的 1MHz，可以使用在 2.7V~24V 輸入電壓範圍內。</br>其輸出電流可以通過一個外部電阻進行設定，回饋電壓被調整至 200mV （典型值）。在操作期間，LED 電流可由一個 PWM 輸入信號進行控制，該信號的責任週期決定了回饋系統的參考電壓的大小。</br>為了實現亮度調整， RT8511A 能夠實現 LED 電流的穩定控制，因而在輸出電容上不會出現音訊雜訊。RT8511A 有一個可程式設計的過壓保護端子，用於避免在 LED 開路狀態下輸出電壓超過最大容許值。 RT8511A 可以 WDFN-8L 2x2 和 WDFN-8L 3x3 封裝形式供貨。
