OC5217 30V,800mA 高端电流检测降压 LED 恒流驱动器 DIM 脚 PWM 调光特性曲线 SW 脚与电感电流工作波形 D=1% PWM 调光波形 D=50% PWM 调光波形 OC5217_V1.0 深圳欧创芯半导体有限公司 6 .ocxsemi. OC5217 30V,800mA 高端电流检测降压 LED 恒流驱动器 应用指南 工作原理 OC5217 是一款内置 30V 功率开关的高端电流检测降压型高精度高亮度 LED 恒流驱动控 制器。系统通过一个外接电阻设定输出电流，最大输出电流可达 0.8A；电流检测精度高达±3%； 外围仅需很少的元件。 系统上电后，定义差值： v VIN VCS (1) 通过典型应用可以看到，负载 LED 上的电流与电感 L 电流以及电阻 RCS 上的电流相等。 上电后，电感电流不能突变，故电阻 RCS 上的电流为零，于是差值 v 亦为零；此差值输入到.
