RT8812 是針對高性能圖形處理器和電腦應用進行了優化的2/1相同步 Buck PWM 控制器，集成了固定導通時間（COT）PWM 控制器、包含自舉二極體的兩組 MOSFET 驅動器、通道間電流平衡電路和過壓保護、欠壓保護、電流限制、熱關機等功能於 WQFN-32L 3x3 封裝中。它採用了 R<sub>DS(ON)</sub> 電流檢測技術，這被用於精確的通道間電流平衡中。電流限制則基於對電感電流的連續感知，使不同的電流取樣方法分貝得到最佳的利用。它採用外部參考輸入和 PWM-VID 動態輸出電壓控制技術，使其回饋電壓得到調節並跟蹤外部輸入的參考電壓。它還具有可調的開關切換工作頻率、動態相數控制、內部軟啟動、Power Good 指示和使能功能。
