Cxle87137 is a fixed pattern 12 channel LED constant current drive IC. The internal oscillator of the product, PWM output for brightness gradient. The chip has synchronous input and synchronous output terminals, which can be connected with AC synchronization or self synchronization of multiple chips. After power on reset, PWM waveform is output, 12 channel led cycle control in turn to achieve meteor and water drop effect. The chip is equipped with 5V regulator, and the out port is driven by constant current 32mA. The peripheral devices are simple and the design is simple, which is suitable for decorative color lamp. This product has excellent performance and reliable quality
