The CYT8000C is an LED constant current driver IC that can adjust the brightness/color temperature in 3 stages. Applicable to AC 180V-240V or AC90V-130V input voltage, constant current accuracy is less than 3%. When the CYT8000C is used in 3-band brightness adjustment, the output current can be changed according to the power on/off, so that the brightness of the LED lamp can be changed. The adjustment ratio can be adjusted by an external CS resistor.
When the CYT8000C is used in the 3-segment color temperature adjustment, the power supply can be turned off according to the turn-on, and the switch state/current of the two output ports can be changed in turn, so that the LED lights of the two different color LEDs are alternately turned on and off to realize the adjustment color temperature function, and the external REXT is adjusted. The resistor sets the output power.
CYT8000C has a simple design structure with over-temperature, over-voltage and other protection functions. It does not require transformers and electrolytic capacitors. The driver solution requires only a few components on the periphery, and can realize all SMT processing, enabling full automation.
