RT6576A/B 是雙通道 Buck 控制器，用於為電池供電的系統生成穩定的電壓。其中包含兩組輸出電壓 2V~5.5V 可調的 PWM 控制器和兩組固定 5V/3.3V 輸出的線性穩壓器，每組線性穩壓器可輸出最大 100mA 的電流，3.3V 線性穩壓器在輸出電流低於 35mA 時的穩壓精度可達 1%。它還包含了一個可用於外部電荷泵電路的振盪器輸出，具有集成化的上電時序控制功能、內部軟起動功能和防止關機以後出現負壓的輸出軟放電功能。由於採用固定電流漣波的 PWM 控制技術，它在工作時無需使用電流檢測電阻，對付再瞬變具有 100ns 的回應速度。為了獲得最高的轉換效率，RT6576A/B 在輕載條件下自動進入二極體模擬模式工作。其封裝為 WQFN-20L 3x3。
