FP7183平均电流模式控制的LED驱动IC工作在恒定关断时间模式。FP7183不产生峰值平均误差，从而大大提高了精度，线路和负载调节LED电流无环路补偿或高边电流检测的需要。输出LED电流精度为2%。 FP7183可以从8.0V供电至100V电源。提供一个PWM调光输入，以接受外部控制TTL兼容信号。输出电流可以通过一个内部250mv参考程序。
The FP7183 is an average current mode control LED driver IC operaTIng in a constant off-TIme
mode.FP7183 does not produce a peak-to-average error，and therefore greatly improves accuracy，
