Cirrus Logic Inc. (Nasdaq: CRUS) has introduced its second
family of digital LED controllers with digital TruDim™ dimmer
compatibility technology designed to accelerate worldwide adoption
of LED retrofit bulbs. In addition to providing near 100 percent
compatibility with the world’s installed base of dimmers, the new
CS163X family provides two-channel LED color mixing capabilities.
This allows LED bulb manufacturers to more efficiently create warm,
natural light quality while also lowering the cost barrier for
two-channel LED retrofit bulbs.

The CS163X family enables improved color quality at up to 30
percent greater efficacy than with single-channel white LEDs. An
innovative digital architecture provides the CS163X family with the
ability to control two LED strings using components typically used
to control a single LED string, resulting in lower system costs
compared to today’s two-channel solutions. In addition, the CS163X
incorporates powerline calibration technology, allowing
manufacturers to calibrate bulb characteristics such as light
output and color temperature by sending commands via the AC mains
terminals during the final manufacturing stage. This patent-pending
technology allows manufacturers to utilize LEDs with a wider
variation in performance characteristics, resulting in lower LED
costs while maintaining consistency in light output and color
temperature from bulb to bulb.
“Cirrus Logic’s CS163X two-channel, TRIAC dimmable digital LED
controller is a breakthrough in digital controllers and an ideal
system solution for our Brilliant Mix technology,” said Horst
Varga, Applications Engineering, OSRAM Opto Semiconductors.
“CS163X’s high level of integration and performance enables many
new opportunities for the Brilliant Mix technology in LED retrofit
applications requiring high color rendering index (CRI) and high
efficacy. The combination of these technologies will accelerate the
growth of LED bulbs that match the natural light color quality
performance of today’s incandescent and halogen bulbs.”
Cirrus Logic entered the LED market in March 2012 with the first
product in its roadmap of LED controllers, the CS161X family, which
focused on solving dimmer compatibility issues. Fundamental to
Cirrus Logic’s LED product family is the company’s digital TruDim
technology, which was the result of a three-year investment in
TRIAC interface algorithms, LED driver topologies and system
architectures. TruDim digital intelligence allows the controller to
identify the type of dimmer in use and adapt its dimmer
compatibility algorithm to provide smooth dimming in much the same
way the consumer has come to expect from decades of using
incandescent light bulbs.
“Cirrus Logic’s roadmap of digital LED controllers is helping
LED retrofit lamp manufacturers accelerate consumer adoption by
solving critical challenges such as dimmer compatibility and color
quality,” said Will Draper, strategic marketing manager for LED
Lighting Products. “The CS163X family builds upon the near-perfect
dimmer compatibility of our first family of digital LED drivers,
the CS161X family, by adding two-channel color mixing technology to
create improved light quality with up to 30 percent more energy
savings compared to single-channel white LED bulbs. Having
established performance benchmarks in both dimming and color
quality, future generation products will focus on lowering system
costs while maintaining this performance leadership.”
Market Background
LED retrofit bulbs are considered by many as the heir apparent
to incandescent and compact fluorescent lamps, due to their
superior energy efficiency and long life. Key barriers to mass
adoption have been higher cost and, like compact fluorescent lights
(CFL), poor dimmer compatibility and color quality. The challenge
posed by color quality improvements represents a significant
opportunity for solid-state lighting (SSL) technology, given that
consumers are largely dissatisfied with the color quality
performance of existing CFLs. Improved color quality is a
fundamental advantage for LEDs due to their more uniform optical
characteristics. As a result, SSL products can more closely
replicate the user experience of incandescent lighting by
simultaneously delivering warm correlated color temperature (CCT)
with high Color Rendering Index (CRI).
Market analyst firm Datapoint Research estimates that the LED
lamp market in ambient lighting applications will grow from around
200 million units in 2011 to around one billion units by 2015.
Pricing and Availability
The CS163X is currently in volume production. It is available in
a 16-pin SOIC package and is priced at $1.06 (USD) in quantities of
100,000.
