TI introduces new LED-lamp Reference Board for dimmable offline lighting applications in collaboration with Lemnis Lighting
Texas Instruments Incorporated introduced a complete LED lighting driver reference board in collaboration with Lemnis Lighting to help address three important issues: cost, dimming and efficacy. The TPS92010 LED-lamp Reference Board applies TI’s semiconductor technology for general LED lighting and Lemnis Lighting’s expertise in dimmable lighting applications.
The board can help speed adoption of energy-saving retrofit LED light bulbs.
The reference board will be available in mid-second quarter and is accompanied
by a user’s guide that contains the schematics, bill of materials and test
results needed to design a dimmable LED lamp.

The reference board is based on TI’s new TPS92010 LED lighting controller.
The TPS92010 offline LED lighting controller implements quasi-resonant flyback
power converters to achieve high efficiency of up to 87 percent, small size and
lower cost for AC/DC LED lighting drivers. The TPS92010’s control technique
allows designers to develop replacement light bulbs in tight, small form factors,
and helps reduce overall system cost. The device’s system-level features, such
as overvoltage detection and shutdown, prevent system damage caused by an open
LED string. Its over-temperature shutdown feature protects against excessive
heat in the system.
“The TPS92010 is helping achieve industry-leading lumens, efficacy, color
temperature and dimming performance in Lemnis Lighting’s Pharox® line of omni-directional
LED replacement bulbs (A19-E26/27 form factor),” said Remko Gaastra, chief
executive officer of San Francisco and Netherlands-based Lemnis Lighting B.V.
“This solution will deliver the optimal balance between power, size and
efficiency to help accelerate the trend to replace traditional light bulbs with
energy-saving LED bulbs."
The TPS92010 is the first of a new family of TI LED controllers designed for
general lighting applications, such as residential LED fixtures; retrofit LED
bulbs; commercial troffers; down-lights; wall sconces; pathway lighting;
overhead lighting; and architectural and display lighting.
“TI is now applying years of experience in LED backlighting to deliver
efficient power management solutions for the rapidly-growing general LED
lighting market,” said Tim Goodrow, general manager for TI’s Power Supply
Solutions group. “The TPS92010 and the TPS92010 LED-lamp Reference Board
demonstrate TI’s commitment to helping our customers solve their lighting design
challenges, and they complement our broad portfolio of power management devices,
wired and wireless interfaces, and embedded processors for lighting applications.”
Building on the successful development of the TPS92010 LED-lamp Reference
Board, TI and Lemnis Lighting will continue to collaborate on future cutting-edge
driver solutions for LED lighting applications.
Key features and benefits of the TPS92010 LED-lamp Reference Board
- The TPS92010 LED-lamp Reference Board features a seamless, high-performance
dimming interface to TRIAC (triode for alternating current) based wall dimmers.
- The TRIAC dimming interface circuit maintains high efficiency even during
deep dimming (60 percent efficient at 10 percent LED current).
- The reference board is an isolated driver with low EMI to simplify safety
certification and electromagnetic compatibility (EMC) compliance. To order the
TPS92010 LED-lamp Reference Board see

Availability and pricing
- The TPS92010 LED-lamp Reference Board will be available in mid-second
quarter and is priced at $49.95. The TPS92010 offline LED lighting controller
is available now in an 8-pin SOIC package and is priced at $0.43 in quantities
of 1,000.
