電荷泵 + 4通道100mA LED 恒流驅(qū)動器

RT9378 是包含了 x1/x1.5/x2 升壓模式的電荷泵和低壓差恒流源的4通道 LED 驅(qū)動器，可為4只 LED 提供穩(wěn)定一致的電流供應，每個 LED 通道的電流最大可達 25mA。它因具有 x1/x1.5/x2 多種升壓模式和低壓差的電流調(diào)節(jié)器而能維持最高的轉(zhuǎn)換效率，當需要調(diào)光時，可用普通 CPU 的 GPIO 端子生成 PWM 信號來對它進行調(diào)節(jié)以實現(xiàn) LED 的亮度控制。\n\nRT9378 的可用封裝是 WQFN-12L 2x2 的，小型的 0.22μF 電容可被用作泵電容與之配合工作，這為便攜式設備提供了一個空間占用很少的高效背光驅(qū)動方案。 ? 在鋰離子電池的全電壓范圍內(nèi)提供了效率高達93%的 LED 驅(qū)動方案\n? 支持多達4只 WLED\n? 總輸出電流高達 100mA\n? 恒流源電壓降典型值為 60mV\n? 0.7%的 LED 電流一致性\n? 輸入噪聲低，EMI 問題少\n? 加電/模式轉(zhuǎn)換時無沖擊過程\n? 0.4μA 低停機電流\n? 符合 RoHS 規(guī)范，不含鹵素;
