CirrusLogic today announced the introduction of the CS161X family of LED controllers to formally enter the emerging high-growth LED lighting market. The CS161X family of controllers uses CirrusLogic's new digital TruDim technology and has been proven to be nearly 100 compatible with many global dimmers. And it can directly solve the dimming compatibility problem, which is also the main obstacle for consumers to adopt LED bulbs. CirrusLogic is currently mass producing CS161X controllers for a leading lighting company. CirrusLogic expects to deliver between 5 million and 10 million LED controllers to multiple customers in 2012.

CirrusLogic Introduces Digital LED Controller Officially Enters LED Lighting Market
LED lighting bureaus are widely used in the lighting industry due to their high efficiency of light energy, long life and environmental protection. However, LED lighting also has certain disadvantages, such as high LED cost and insufficient compatibility with general lighting. Today's LED bulbs are based primarily on analog drivers, and none of them offer a wide range of dimming compatibility for consumer installations in residential, retail, and corporate dimmers. The problem of dimming incompatibilities, including flashing, flashing, or inability to switch, is the main cause of high product returns.
Jason Rhode, president and CEO of CirrusLogic, said: A few years ago, we saw the growing LED market as an area where we could leverage our signal processing expertise to solve meaningful engineering challenges. For today's consumers, buying LED bulbs is a frustrating experience, as you can find that most LED bulbs are not available once you buy them home. The challenge of solving dimming compatibility has proven to be extremely complex. We are very pleased to see that one of the world's largest LED lamp manufacturers has demonstrated the superior performance of our first LED controller, which is nearly perfectly compatible with every dimmer we can find and test around the world.
Research firm DatapointResearch estimates that the LED lighting market in lighting applications will grow from about 200 million in 2011 to 1 billion in 2015. Jon Gamble, senior analyst at DatapointResearch, said that achieving LED bulbs compatible with all existing dimming systems around the world is one of the biggest challenges for LED bulb manufacturers. In the next few years, addressing dimming compatibility while maintaining cost-effectiveness is the key to accelerating the widespread adoption of LED bulbs for consumers.
The digital TruDim technology enables industry-leading dimming-compatible CS161X series to deliver outstanding results after three years of investment in TRIAC interface algorithms, LED driver topologies and system architectures, which are the foundation of TruDim technology. The CS161X's digital intelligence allows the controller to identify the type of dimmer in use and adjust the compatibility algorithm to provide smooth dimming in the same way that consumers have used incandescent bulbs for decades. This intelligent adaptive digital signal processing technology is not possible with today's analog controllers.
Dimming compatibility tested to nearly 100 CirrusLogic acquired more than 200 dimmers worldwide and developed a compatibility test to measure the impact of the CS161X on the performance of existing solutions. The dimming compatibility test includes testing of 120V and 230V products, covering multiple and 5-10 bulbs in parallel with multiple lamp configurations. It mainly measures 4 key parameters to determine dimming compatibility: (1) Function (2) None Blinking stable state (3) Smooth dimming and (4) Dimming range (maximum-minimum). CirrusLogic's CS161X performed nearly perfectly throughout the test, achieving 98 compatibility. The closest LED controller compatibility on the market is 71, and the LED controller compatibility average is 50.
CS161X Series Product Information The CS161X is the first in a new line of CirrusLogic LED controller solutions designed to help leading LED luminaire manufacturers address complex engineering challenges and drive sales of high-capacity LEDs. The CS161X family's unique adaptive dimming compatible algorithm controls the boost stage for optimal flicker-free phase dimming over the entire spectrum, including front-end, trailing edge, and digital dimmers for deep dimming down to zero. Light output.
The CS161X integrates a variable conduction mode boost converter (CRM/CCM) that provides power factor correction and dimmer compatibility with side control, constant output current, quasi-resonant flyback or buck output stage, and is suitable for 100 -120VAC and 220-240VAC line voltage solutions.
CirrusLogic's first LED driver family addresses the challenges of dimming compatibility. Subsequent products in the company's product blueprint will improve LED color and reduce system cost to meet industry demand, highlighting the company's long-term investment in LED products.
