电荷泵 + 4通道100mA LED 恒流驱动器

RT9378 是包含了 x1/x1.5/x2 升压模式的电荷泵和低压差恒流源的4通道 LED 驱动器，可为4只 LED 提供稳定一致的电流供应，每个 LED 通道的电流最大可达 25mA。它因具有 x1/x1.5/x2 多种升压模式和低压差的电流调节器而能维持最高的转换效率，当需要调光时，可用普通 CPU 的 GPIO 端子生成 PWM 信号来对它进行调节以实现 LED 的亮度控制。\n\nRT9378 的可用封装是 WQFN-12L 2x2 的，小型的 0.22μF 电容可被用作泵电容与之配合工作，这为便携式设备提供了一个空间占用很少的高效背光驱动方案。 • 在锂离子电池的全电压范围内提供了效率高达93%的 LED 驱动方案\n• 支持多达4只 WLED\n• 总输出电流高达 100mA\n• 恒流源电压降典型值为 60mV\n• 0.7%的 LED 电流一致性\n• 输入噪声低，EMI 问题少\n• 加电/模式转换时无冲击过程\n• 0.4μA 低停机电流\n• 符合 RoHS 规范，不含卤素;
