High Voltage LED Constant Current Source IC HA****4P Constant current source IC is a kind of power supply convertor of constant current source. This constant current source IC mainly apply to supply power of LED in series.The mumber of LED in series can up to **0. It voltage is AC *5V~**0V,output a constant current that the value can be preseted by outer circuit is concise,the whole circuit structure is very small in volume with no inductance and transformer, can be seted in small volume of LED lamps and lanterns. All kinds of forms, sizes and current parameters can be satisfied that are required by the clients. Features:- 1. Range of Input Voltage:*5VAC~**0VAC. (AC Input Only ) 2. Range of output constant current:*0mA~*0mA;(Presented by outer circuit) 3. Range of Temperature:**0&#***1;~*5&#***1; 4. Precision:±2.5%;±5% ;±*0% 5. Efficiency:*5% (With resistance load situation) 6. Range of the number of LED in series: n&#***4;0.9VinDC/VF (n is the number of LED in series single circuit ; VinDC is the voltage of commutate output; VF is forward voltage drop of every LED). 7. Volume:DIP**0 8. Stability is very good ,high performance cost ratio,the useage performance parameter is not unchanged in large range working voltage and temperature. 9. Good property of EMC *0. Applications *1. LED lighting set *2. Electronic display *3. Industry lighting facility *4. Decorative lighting facility and bulb. *5. LCD Plane display backlight *6. Others LED driver of without isolation form power supply.
