A new DCL2118 can replace the traditional power IC

1 LED driver power chip: DCL2118 LED driver chip, integrated, modular, digital. Lead the LED industry revolution

2 LED constant current drive IC DCL2118 UHV transmission line transformer ACtoDC equipment and free LED constant current function of the drive system. An external inductor, transformer and rectifier diode can be removed to change the need for LED lighting applications:

DCL2118 7mm´ 7mm

Applications: LED fluorescent tube T8 (lamp, lamp etc.)

The circuit is a bit more complicated than the traditional

The 1 is 23Pin 7mm´ 7mm TQFN package: the full name of small leadless quad flat package.

2 DCL100VAC to 140VAC, DCL2118200VAC to 250VAC.DCL2118 programmable constant output current.

3 their internal four channel digital circuit to achieve high power factor PF:0.99

4 can be achieved by using different internal program duty cycle pulse width modulation dimming control.

5 DC constant current drive AC

6 transformer design: wide input voltage range: 100VAC-140VAC/200VAC-250VAC

7 constant current accuracy: +-10%

8 LED driver: 20mA-120 Ma DCL2118

9 high power factor: PF:0.99

10 total harmonic distortion (THD): about 10%

11 automatic synchronous 50HZ / AC 60HZ input frequency control

12 LED constant current drive power compensation and protection

13 working temperature: -40 degrees C- +85 C

The advantages of DCL 2188 are as follows:

1 LED lamp life

DCL2118 is 1 billion (available for test data). (traditional power of time is 2-3 million hours)

Digital circuit 2 their internal four channels to achieve high power factor. (PF: 0.99)

3 customers in the use of relatively simple design and convenient (in the production operation process can enhance the efficiency of energy efficiency can be improved: 85-93%)

4 IC actual cost is relatively low.

5 solve the size of the traditional power supply, high calorific value determination

6 total harmonic distortion (Xie) wave THD. (about 10%)

The IC (non isolated) can directly replace LED energy-saving lamp power supply (SMPS), the current is very stable, low working temperature, the service life of the product can be up to 100 thousand hours, directly to customers to save the production cost, but also facilitate production control, smaller volume, easy to export, this industry into a landmark reform the.
