RT8301 是具有動態餘量控制（ DHC ）功能的8通道定電流吸入 LED 驅動器，它能提供良好的通道間電流一致性，可通過調節 VSET 電壓設定合適的 MOSFET/BJT 電壓差。此外， DHC 提供了穩定的 VFB 調節，這使得即便是在調光期間也能保持很小的電壓漣波。<br>RT8301 的8個通道之間的電流誤差範圍在3%以內，在不同晶片之間也保持這一水準。各通道的輸出電流可通過一隻外部電阻（ RISET ）進行調節。 LED 的亮度還可以通過施加在 EN/PWM 端的責任週期範圍為 0%~100% 的 PWM 信號進行調節。 RT8301 可以借助外部元件實現大電流操作滿足應用需求。
