TM1913是具有内控同步功能的三通道LED固定18mA恒流驱动IC，信号输入断开后实现同步固定七彩

花样变化，可防止芯片损坏导致的后续级联芯片不工作。同时适合制作全内控灯条，无需控制器。芯片

内部集成有MCU固化程序和单线数字接口、数据锁存器、LED恒流驱动等电路。VDD引脚内部集成5V稳压

管，外围器件少。适用于护栏管、点光源等LED装饰类产品。本产品性能优良，质量可靠。-TM1913 is a three-channel constant current LED 18mA with a fixed internal synchronization function driver IC, synchronized signal input is disconnected after fixed Colorful

Mood changes, to prevent damage caused by subsequent cascade chip chip does not work. At the same time suitable for making the whole internal control lights, without the controller. Chip

Internal integrated MCU firmware and wire digital interface, data latches, LED constant current driver circuit. VDD pin integrated 5V regulator

Tube, less peripheral devices. Suitable for tube, point light source LED decorative products. This product is excellent performance, reliable quality.
