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.
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: n0.9VinDC/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
Precision:± 2.5%;± 5%;± 10%
Good property of EMC
Range of Temperature-40 ℃~ 85
Good stability, high performance cost ratio, and the usage perrfomance
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

Explain
1.VF0.9Vin, VF is forward voltage drop of each LED.
2. For the type HA22002PB(20mA)IC the total voltage drop of a LED string more
than 30V is better. That means the number of LEDs in series need more than
16pcs in a loop (the red LED work voltage is 1.8V).For the type HA22004PB(40mA

HA22006PB(60mA) IC the total voltage drop of a LED string more than 90V is
better.If there are two or several LED string merging, each string should with the
same number of LEDs.
3. The best range of output constant current source: 150V-180V.

The Relationship of Current and Resistance
5. Resistance R2:resistance value=0.8*input voltage*1K (range of resistance
±5﹪) , power value: 1W.example:when Vin=220V ,R2=220*0.8=180 K. (It's
better for the IC away from the resistances R1 and R2 when design.)
6. R3 is the current compensatory resistance, recommend use 10 K1/16W ~
1/8W resistance .
7. C2: Filter capacitance(the recommendation is 1~4.7uF/400V )
8. C1:Smoothing capacitance(For the types of HA22002P and HA22004P,
peripheral capacitance C1 is 100uF/16V,and HA22006P, peripheral capacitance
C1 is 100uF/25V)
9. Warning note: don't use Filter Capacitance follow the bridge circuit.
10. The method of how to count out the most number of LED it can bring with
example: Suppose input voltage VinAC=220V,then VinDC = 220 V×0.9 = 198 V.
For example drive white LED light, suppose each white light Vr=3.3V, thus, it can
bring 198V/3.3V=60.If the electrical network voltage is low when voltage supply,
in order to ensure IC has enough adjustment scope to drive the LED to be able th
normal work , This time above mathematical formula While coefficient 0.9.
VF = 198V × 0.9 =178V. Now the most number of white LED light it can drive can
achieve 178V/3.3V=54. This computational method has considered ViAC±15%
range of variation. If the AC input is under the stabilzed voltage, the quantity of
LEDs can be added more.
11. The first pin is Enable port, effectual when vacant and turn off when on high lev
This pin can not connect with low level. The following circuit diagrams are two
modes to enable the IC. Fig (a) is for segregated mode enabling, Fig (b) is for
un-segregated mode enabling.
Remark: When using EN pin to control the circuit on or off, add an inductance to lim
the current ascender (di/dt). Red LED obvious in particular under this protect effec
Its value can be 1 to 2.2mH, and the max permissible current should be more 1.3
times actual current across the LED load.
