CYT1012BM is a single-segment linear LEDconstant-current driver chip with built-in constant-power function without external powercompensation resistance. When the inputvoltage is too high, the series current of LEDlamp will be automatically reduced to ensure thatthe input power is basically unchanged and thethermal stability of the system is guaranteed.The chip has the function of overtemperatureadjustment to improve system reliability. Systemstructure is simple, peripheral components less,cost-effective scheme.

The output constant current ranges from5mA to 185mA

The constant current accuracy deviation

between chips is less than t5%
