HA22004PB

HA220XXPB High Voltage LED Constant Source IC General Description 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. The input voltage is 85-240VAC,output a constant current that the value can be preset by peripheral resistance. The peripheral circuits is concise, the whole circuits structure is very small in volume wi th no inductance and transformer, which can be set in LED lamps and lanterns with a small volume. www.DataSheet4U.com Features ►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 performance cost ratio, and the usage perfo rmance parameter won't change in large range working voltage and temperature ►Package: DIP-10 Applications ►LED lighting device ►Electronic display ►Industry lighting facility ►Decorative lighting facility and bulb ►LCD Plane display backlight ►Other LED driver that needn't isolated from power supply Block Diagram ...
