LED Controller and Driver facilitate retrofit bulb design.February 19, 2013 -
Offered in 6-pin TSOT package measuring 2.9 x 2.9 mm, Model TPS92075 is designed for phase-dimmable, offline AC/DC LED lamp and downlight applications such as E14, GU10, A19, and PAR20/30/38 bulbs. Constant-current lighting controller achieves power factor correction above 0.9 while delivering flicker-free dimming when used with conventional wall dimmers. Supplied in 10-pin PowerPad™ MSOP package, Model TPS92560 is intended for low-voltage AC or DC LED lamp applications such as MR16 and AR111.

Industry's smallest and easy-to-use drivers reduce component count and solution size
DALLAS, -- 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 information on LED replacement lamp and downlighting solutions, visit www.ti.com/ledretrofit-pr .
Key features and benefits of TPS92075 and TPS92560:
-- TPS92075 for E14, GU10, A19 and PAR20/30/38 bulbs
-- TPS92560 for MR16 and AR111 bulbs
- Small 6-pin TSOT package measures 2.9 mm by 2.9 mm.
- Step-down (buck) or step-up/step-down (buck-boost) operation suitable for 120-VAC or 230-VAC LED lamps and downlights.
- Power factor correction greater than 0.9 meets regulatory requirements for lighting.
- Flicker-free dimming compatible with TRIAC and trailing-edge dimmers.
Availability, packaging and pricing
- Simple hysteretic input current control scheme requires no complicated loop compensation and enhances compatibility with electronic transformers.
- Integrated active low-side input rectifiers improve efficiency, simplify design and lower bill of materials.
- Step-up (boost) or step-up/step-down (SEPIC) operation suitable for use with a variety of LED loads
The TPS92560 and TPS92075 are available in volume now from TI and its authorized distributors. Offered in a 10-pin PowerPad(TM) 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.
