CIRRUS LOGIC ENTERS LED LIGHTING MARKET WITH
DIGITAL CONTROLLER DELIVERING NEAR 100 PERCENT TRIAC DIMMER
COMPATIBILITY
In Volume Production Today with Tier-1 Lighting
Company, CS161X Family of LED Driver ICs Uses New TruDim Technology
to Help Speed Worldwide Adoption of LEDs
Cirrus Logic Inc. (Nasdaq: CRUS) is entering the emerging
high-growth LED lighting market with a digital LED controller that
directly solves dimmer compatibility issues that have been a major
barrier to consumer adoption of LED retrofit bulbs. Featuring
Cirrus Logic’s new digital TruDim™ technology, the CS161X
controller family has been tested to provide near 100 percent
compatibility with a wide array of dimmers representing the vast
majority of the installed base worldwide. The CS161X is already in
high volume production with a tier-1 lighting company. Cirrus Logic
expects to ship between 5-10 million LED controllers during
calendar year 2012.
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 fluorescents, poor
dimmer compatibility. None of the LED bulbs available today, which
are primarily based on analog controllers, provide consumers broad
compatibility with the wide variety of dimmers installed within
residences, retailers and businesses. Dimmer incompatibly problems,
which include bulbs that produce flickering or flashing light or
the inability to turn on or off, are a leading cause for high rate
of return by consumers.
“Several years ago Cirrus Logic identified the growing LED
market as an area where we could leverage our signal processing
expertise and solve meaningful engineering challenges,” said Jason
Rhode, Cirrus Logic president and CEO. “To the consumer, buying an
LED lamp today can be a frustrating experience because so many of
them just don’t work once you take them home. As it turns out,
solving the challenges of dimmer compatibility was enormously
complex, and we're pleased that one of the largest LED lamp
manufacturers has showcased our first LED controller precisely
because it provides near-perfect compatibility with every installed
dimmer from around the world that we could find and test.”
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.
“Making LED light bulbs nearly universally compatible with all of
the dimmer systems that currently exist around the world is one of
the biggest challenges facing LED bulb manufacturers," said Jon
Gamble, senior analyst, Datapoint Research. “Solving dimmer
compatibility whilst maintaining a competitive bill of materials is
key to accelerating the LED market toward widespread consumer
adoption during the next few years.”
Digital TruDim Technology
The CS161X family enables industry-leading dimmer compatibility
as a result of a three-year investment in TRIAC interface
algorithms, LED driver topologies and system architecture, which
are the foundation of TruDim technology. The CS161X’s 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. This smart adaptive
digital signal processing technology is not possible with today’s
analog controllers.
Near 100-Percent Tested Dimmer Compatibility
Cirrus Logic acquired more than 200 dimmers from all over the
world and developed a compatibility test to measure the performance
of existing solutions against the CS161X products. This dimmer
compatibility test, which involves the testing of 120V and 230V
products, in single and multilamp configurations of five and 10
lamps in parallel, measures five key parameters for determining
dimmer compatibility: (1) functionality (2) flicker-free steady
state (3) smooth dimming and (4) dimming range (max-minimum).
Cirrus Logic’s CS161X performed near flawlessly across the test’s
metrics, achieving 98 percent compatibility. The closest
competitive LED controller performed at 71 percent, and the average
among today’s current LED controllers was 50 percent.
CS161X Family Product Information
The CS161X is the first family of products in Cirrus Logic’s new
line of LED controller solutions designed to help leading LED lamp
manufacturers solve complex engineering challenges and drive
high-volume LED sales growth. The CS161X family’s unique adaptive
dimmer compatibility algorithm controls the boost stage to enable
best-in-class flicker-free phase dimming across the light spectrum,
including “deep dimming” down to zero percent of light output with
leading edge, trailing edge and digital dimmers.
The CS161X integrates a variable conduction mode boost converter
(CRM/CCM), providing power factor correction and dimmer
compatibility with primary-side control, constant output current
and quasi-resonant flyback or buck output stage and includes
solutions for both 100-120 VAC and 220-240 VAC line voltages.
While Cirrus Logic’s first LED driver family solves the dimmer
compatibility challenge, subsequent products in the company’s
roadmap are planned to address industry demands for improved LED
light color and system cost reduction, showcasing the company’s
continued long-term investment in LED products.
Pricing and Availability
The CS161X is currently in volume production. It is available in
a 16-pin SOIC package and is priced at $0.81 (USD) in quantities of
100,000.
