Clare pushes up to 550V LED driver control IC to drive 100 series LED clusters

Clare has introduced the LED driver control IC "CPC9909N" with an input voltage range of +8 to 550V. It can control the driving from several series LED groups to more than 100 series LED groups. Of course, it is also possible to control the drive of the parallel group. Used for ordinary LED lighting fixtures, backlights for large-screen LCD monitors, and digital signage.


LED driver control IC with input voltage up to 550V
The new products are manufactured using BCDMOS (Bipolar/CMOS/DMOS) process technology developed by the company. The manufacturing process with a withstand voltage of +550V is adopted, and the bottom plate is SOI (Silicon On Insulator). Integrated voltage regulator circuit. The input voltage is stepped down by the circuit for use in the chip.
The new product uses a PFM (Pulse Frequency Modulation) control method that maintains a peak current at a certain level. The duty cycle can be set to a maximum of 50%. A gate drive circuit with a built-in power MOSFET. The power MOSFET needs to be external. The current supplied to the LED can be set with an external resistor. More than 90% conversion efficiency can be obtained with this control IC. Dimming is also available. Two control modes are supported. One is a linear way of inputting a DC voltage for control. The other is the PWM method of inputting the PWM signal for control.
The new product is available in an 8-terminal SOP package. The unit price for 10,000 batch purchases is $0.63. In addition, the "CPC9909NE" is available in an 8-terminal SOP package with improved thermal characteristics. The unit price for 10,000 batch purchases is $0.72.

Dual Color Controller are generally designed voltage 12V-36V, the number of each circuit LED 3-6 in series, current limiting resistor buck, each loop current of 20mA or less. A product of a plurality of LED circuit LED, the advantage of low pressure, simple structure, easy to design; 

Dual Color Controller

Dual Color Controller Drawback is: when the current large scale product, you need to configure the low-voltage switching power supply. Due to the limited shortcomings of products, low-voltage long-distance transmission is not possible, all led light bar controller [1] is limited to the small size of the product, such as text signs, small patterns and so on. According to this feature.


The controller design specifications of Dual Color Controller : 12V selection of 75A / 30V MOS power of control, the output current 8A / Road; 24-36V selection 60A / 50V MOS power of control, the output current of 5A / road. Users can control large ones selected according to the above specifications of Dual Color Controller, the transitions can choose to buy NE10 NE20 series of low pressure to low pressure controller series, the gradient. Note that LED must be common anode (+) pole connection method, controller Yin (-) pole, the controller does not include low voltage power supply.

Features Dual Color Controller to control more than large ones, to control the use of the serial signal transmission purposes, the general control unit 512 need only four control connection, serial LED controller LED light sources require board register with the controller can choose models NE040S controller, the controller has reached maximum capacity 4096KBit, if the load 512 LED unit 8192 can achieve maximum picture frame.


Mingxue Optoelectronics Co.,Ltd. has apply the I S O 9 0 0 1: 2 0 0 8 international quality management system certificate, for Dual Color Controller we apply the CE, RoHS and SAA certificate for our led lighting product.
