1ch DC/DC 降压LED驱动器

LC5901S是OFF时间由外部设定的脉冲比率控制(PRC)的采用平均电流控制的降压型1ch输出LED背光用控制器IC，与外置MOSFET组合使用。作为本产品控制方式的优点，与检测电感电流峰值的电流模式不同，无须斜坡修正和外部相位补偿等。因此，用较少的外部元件即可实现高效率、高精度的LED驱动。备有充足的保护功能，可广泛应用于LED电路构成，可对应模拟/PWM调光。该IC是薄型小型的SOP8表面贴装型封装｡ ･电源电压范围：7～18V\n･动作方式：TOFF由外部設定的PRC方式的平均电流控制\n･无须外部相位补偿\n･OFF时间(TOFF)调整范围：1.0～9.0μs\n･调光功能：PWM调光／模拟调光\n･电流基准精度±2%\n･OCP：Pulse by pulse～Auto restart\n･LED串联应用Open保護：限制最大ON时间～Auto restart\n･UVLO：Auto restart\n･过热保护(TSD)：Auto restart\n･封装：SOP8;
