TI's new LED drivers simplify retrofit light bulb design
Industry's smallest and easy-to-use drivers reduce component count and
DALLAS, Feb. 12, 2013
DALLAS, Feb. 12, 2013 /PRNewswire/ --Texas Instruments Incorporated (TI)
(NASDAQ: TXN) today introduced the industry's smallest off-line,
phase-dimmable, constant-current lighting controller and an easy-to-use
lighting driver that simplify the retrofit of a variety of LED bulbs,
including E14, GU10, A19, PAR20/30/38, MR16 and AR111. The TPS92075 controller
and TPS92560 driver reduce component count and solution size while improving
compatibility with legacy lighting controls. For more information and samples,
visit www.ti.com/tps92560-pr and www.ti.com/tps92075-pr.
The TPS92075 is designed for phase-dimmable, offline AC/DC LED lamp and
downlight applications. Offered in a very small 6-pin TSOT package, it
achieves power factor correction above 0.9 while delivering smooth,
flicker-free dimming when used with conventional wall dimmers. The TPS92560 is
intended for use in low-voltage AC or low-voltage DC LED lamp applications
such as MR16 and AR111. It uses a proprietary input current control method,
which improves compatibility with electronic transformers.
The TPS92075 and TPS92560 join TI's LED driver portfolio for retrofit bulbs
that includes the LM3445, LM3447, TPS92310/11/14, LM3444 and LM3401. For more

Key features and benefits of TPS92075 and TPS92560:
oTPS92075 for E14, GU10, A19 and PAR20/30/38 bulbs
oSmall 6-pin TSOT package measures 2.9 mm by 2.9 mm.
oStep-down (buck) or step-up/step-down (buck-boost) operation suitable
for 120-VAC or 230-VAC LED lamps and downlights.
oPower factor correction greater than 0.9 meets regulatory
requirements for lighting.
oFlicker-free dimming compatible with TRIAC and trailing-edge dimmers.
oTPS92560 for MR16 and AR111 bulbs
oSimple hysteretic input current control scheme requires no
complicated loop compensation and enhances compatibility with
oIntegrated active low-side input rectifiers improve efficiency,
simplify design and lower bill of materials.
oStep-up (boost) or step-up/step-down (SEPIC) operation suitable for
use with a variety of LED loads.
Availability, packaging and pricing
The TPS92560 and TPS92075 are available in volume now from TI and its
authorized distributors. Offered in a 10-pin PowerPad™ MSOP package, the
TPS92560 is priced at US$0.72 each in 1,000-unit quantities. Priced at
US$0.75, the TPS92075 is offered in an 8-pin SOIC package, and a small 6-pin
TSOT package that will be available in March.
