Plath launches AC-DC series power supply controller for dimmable LED lighting

In April 22, 2010, before the match Plath semiconductor company announced the launch of AC-DC for digital power controller of LED lighting. The CY8CLEDAC01/02 controller provides a cost-effective solution for dimmable and dimmable LED lighting with high efficiency and EnergyStar requirements. They can carry out automatic dimming detection, which can be used in conjunction with the existing mainstream wall dimmer, the minimum can be reduced to 2% and no flicker.

The new AC-DC controller has a "main side sensing" (primary-side) function, and can adjust the LED current, so as not to isolate and other two level edge (secondary-side) control circuit. This technique reduces the number of components required to the limit, reducing the board size, power consumption, and overall hardware cost compared to other isolated solutions. The new controller also has a circuit protection function, which is often not available in other "main side induction" solutions. This built-in protection feature includes over voltage protection (OVP), output short circuit protection (OSCP), peak current limit protection (PCLP), current sense resistor short circuit protection (CSSP), and over temperature protection (OTP). The reference for the design of CY8CLEDAC01 and CY8CLEDAC02, including all the circuit diagram, BOM, Geber file, and all files required for full LED lighting retrofit design of power supply model AC-DC controller expands Sepp Lars's series of lighting products, effective coverage of the modified LED lighting market. They are embedded with the PowerPSoC series power controller, constitute the industry's first high power LED single chip control and drive program. AC-DC product line and Sepp Lars's PowerPSoC series covers a wide range of LED applications, ranging from the LED to the high-end needs of a variety of functions (such as communications, diagnostics, color change, etc.) LED lighting products.

Curtis Plath, vice president of PowerPSoC division, said: "race for the growing LED lighting market to provide differentiated products to meet their unique needs Davis. The AC-DC controller provides a powerful combination of features and performance for the LED retrofit bulbs.

Supply situation

CY8CLEDAC01 (non adjustable light) and CY8CLEDAC02 (adjustable light) controller can now be purchased through the Plath authorized dealer. Both are 8-pinSOIC packages. High resolution images of CY8CLEDAC devices can be obtained from the following URL: www.cypress.com/go/pr/LEDACphoto.
