Cirrus Logic digital LED controller

March 29, 2012 Cirrus Logic company announced the launch of the digital LED controller, officially entered the high growth emerging LED lighting market. The LED controller is able to directly solve the dimming compatibility problem, which is also the main obstacle to consumers using LED bulbs. CS161X series controller adopts new digital TruDim technology Cirrus Logic, and have been tested, and many of the world adjusted close to 100% of the light is compatible. The Cirrus Logic has been a leading lighting company in mass production of CS161X controller. Cirrus Logic is expected in 2012 will be delivered to multiple customers 5 million -1000 000 LED controller.

At present, the main obstacle to the large-scale use of LED bulbs in addition to the cost is more expensive, and compact fluorescent lamp as the compatibility problem has not been resolved is the main problem. The LED bulb is mainly based on the analog driver, can provide consumers installed in residential, retail shops and businesses to provide a wide range of dimmer dimming compatible manufacturers is still relatively small, including lighting flashing, flashing or unable to switch, dimmer compatibility problems are a major cause of high return rate.

Cirrus Logic president and CEO Jason Rhode said: "a few years ago, we have seen growth in the LED market as a field of expertise we can use signal processing to solve significant engineering challenges. For today's consumers, the purchase of LED bulbs is a frustrating experience, because once you buy home and found that most of the LED bulbs can not be used. As it turns out, the challenge of addressing dimming compatibility is extremely complex. We are very pleased to see that one of the world's largest manufacturer of LED lamps have demonstrated the superior performance of our first LED controller, it can be with us in the world to find and implement compatible with near perfect each dimmer test. "

Datapoint Research senior analyst Jon Gamble said: "all LED lighting dimming system and the current global compatibility is one of the biggest challenges for LED lighting manufacturers. The next few years, to solve the compatibility of light while maintaining cost-effective is the key to accelerate the widespread adoption of LED bulbs for consumers. "

Digital TruDim Technology

The industry leading dimming compatible CS161X series is the TRIAC interface algorithm, LED drive topology and system architecture for three years after the investment of outstanding achievements, which is the basis of TruDim technology. CS161X's digital intelligence allows the controller to identify the type of dimmer in use and adjust the compatibility algorithm to provide a smooth dimming through the same way that consumers use incandescent bulbs for decades. The intelligent adaptive digital signal processing technology is unable to realize the analog controller.

The test has close to 100% dimming compatibility

Cirrus Logic bought more than and 200 dimmers, and developed a test to measure the compatibility of CS161X products on the performance of existing solutions. The dimmer compatibility tests include the 120V and 230V test, and 5-10 cover a single bulb in parallel multi lamp configuration, 4 key parameters of the main measurement to determine the dimming compatible performance: (1) function (2) without blinking stable state (3) and (4) smooth dimming dimming range (maximum - Minimum). Cirrus Logic CS161X in the whole test performance close to perfect, reach 98% compatibility. LED controller compatibility closest to the market is up to 71%, LED controller compatibility with an average of 50%.

CS161X series product information

CS161X is the first in a series of Cirrus products Logic LED controller solutions new product line, leading manufacturer of LED lamps designed to help solve complex engineering challenges, and promote high capacity LED sales growth. The CS161X series of unique adaptive dimming control algorithm can be compatible with the boost stage, in order to achieve the best in the whole spectral phase flicker free dimming, including the use of advanced digital dimmer, trailing edge and decreases from "dimming" to the light output of 0%.

CS161X integrated use of a side control variable conduction mode boost converter with power factor correction and dimmer compatibility (CRM/CCM), output current, constant or quasi resonant flyback buck output stage, and solutions for 100-120VAC and 220-240VAC line voltage.

The first series of Cirrus LED drive Logic company to solve the dimming compatible challenges, subsequent products company product blueprint will improve LED color and reduce the system cost in order to meet the needs of the industry, highlighting the long-term investment company for LED products.
