Cxle87139 is a fixed pattern 5-channel 8-20led constant current driver chip. The product has its own oscillator, control circuit and PWM output for brightness gradient. After power on and reset, the chip works immediately, outputs PWM waveform, and circulates all LEDs in turn to achieve meteor and water drop effect. Less peripheral devices, three-level speed setting, suitable for decorative lights. With the new driving mode, 5 output ports can drive up to 20 LEDs
