RT8555 是一款用於白光 LED 的高效率驅動器。它適用於單節 / 兩節電池輸入，以驅動包含六串並聯且每串最多 10 顆 WLED 的 LED 燈條。內部電流汲入器支援最大 ±2% 電流不匹配，可在每串 LED 中實現優異的亮度均勻性。為提供電流汲入器運作所需的足夠餘裕，升壓控制器會監測回授腳位的最低電壓，並調節最佳化輸出電壓以提升電源效率。RT8555 具備 2.7V 至 24V 的寬輸入電壓工作範圍，並包含 I<sup>2</sup>C 介面，用於控制調光模式、工作頻率與 LED 電流。內部 100mΩ、36V 功率開關搭配電流模式控制，可提供過電流保護。RT8555 的切換頻率可在 300kHz 至 2MHz 之間調整，可在效率與元件尺寸之間提供靈活性。RT8555 採用 WL-CSP-20B 1.65 x 2.05 (BSC)，間距 0.4mm 封裝。
