Constant current source IC is a kind of power supply converter with a constant current output.

This constant current source IC is mainly applied to supply power of LEDS in series.

When the input voltage is 220VAC, with red LED, the number of LEDs in series can up to 110.

Wide input range 85 to 240VAC.
>95% efficiency(Test conditon: With resistance load, between IC two ends).
Range of output constant current: 10mA to 80mA(Preset by peripheral circuit).
The number of LEDs series: n≤ 0.9VinDC/VF. n is the number of LEDs in series single circuit ;VinDC is the voltage of commutate input; VF is forward voltage dr of each LED ；± 5%；± 10%.
Precision：± 2.5%.
Good property of EMC ： -40 ℃～ 85 ℃.
Range of Temperature.
Good stability, high p.
