RT6585 是一款雙通道降壓控制器，可為電池供電系統產生供應電壓。其包含兩個可在 2V 至 5.5V 之間調整的脈衝寬度調變 (PWM) 控制器，以及兩個固定 5V/3.3V 線性穩壓器。每個線性穩壓器可提供高達 100mA 的輸出電流，且 3.3V 線性穩壓器在 35mA 以下可提供 1% 精度。RT6585 提供一個模式選擇接腳 SKIPSEL，可選擇二極體模擬模式 (DEM) 或音訊跳脈衝模式 (ASM)。其他特性包括板載上電時序、電源良好輸出、內部軟啟動，以及可在關斷期間防止負電壓的軟放電輸出。<br />定電流漣波 PWM 控制架構無需感測電阻即可運作，並可對負載暫態提供 100ns 響應。為了最大化電源效率，RT6585 會在輕載應用中自動切換至二極體模擬模式。RT6585 採用 WQFN-20L 3x3 封裝。建議接面溫度範圍為 −40°C 至 125°C。
