Setting the Standard for Dimmer Compatibility
Dimmable LED Driver ICs
Cirrus Logic digital LED controller ICs directly solve the dimmer compatibility issues that have been a major barrier to consumer adoption of LED retrofit bulbs. Featuring Cirrus Logic's patented digital technology, the CS161X, CS161XA, CS1615/16, CS1615A/16A, CS1630/31, and CS1680 product families are designed to help leading LED lamp manufacturers solve complex engineering challenges and drive high-volume LED sales growth.
Best Dimming Performance
Cirrus Logic is setting the standard for dimmer compatibility based on a three-year investment to develop a proprietary digital adaptive dimmer-compatibility algorithm, as well as new LED driver topologies and system architectures. This combination makes up the foundation of the patented technology found in all Cirrus Logic LED driver IC families. This core digital intelligence enables these controllers to identify the type of dimmer in use and adapt the algorithm to provide smooth dimming. For consumers, the dimming experience replicates what they have come to expect from decades of using incandescent light bulbs. This smart adaptive digital signal processing technology is not possible with today’s analog controllers.
Near 100 Percent Tested Dimmer Compatibility
Using more than 300 dimmers acquired from all over the world, Cirrus Logic developed a dimmer compatibility test to measure the performance of the CS161X, CS161XA, CS1615/16, CS1615A/16A, CS1630/31, and CS1680 product families versus the current offering of competing LED driver solutions. The following is an overview of the test methodology. All tests were conducted in single and multi-lamp configurations.
Cirrus Logic's patent-pending approach to dimmer compatibility allows for full functionality on all types of dimmers, including leading edge, trailing edge, and "smart" dimmers. In North America, smart dimmers represent some of the most popular models sold today and present unique compatibility problems for competing LED drivers.
CS1610 Family - Two-Stage LED Driver
CS1615/16 Family - Single-Stage LED Driver
CS1630 Family - Two-Channel LED Color Mixing
Prototyping Made Easy
Cirrus Logic reference designs and demonstration boards easily illustrate the performance of the CS161X, CS161XA, CS1615/16, CS1615A/16A, CS1630/31, and CS1680 LED Drivers IC product families featuring best-in-class dimmer compatibility for leading-edge, trailing-edge, center-cut, and smart digital dimmers. These form factors are targeted to fit into many LED bulb applications (GU10, A19, PAR, BR, MR16).
