Texas Instruments dimmer can retrofitted to LED light bulbs

Texas Instruments dimmer can retrofitted to LED light bulbsTI has announced off-line, phase-dimmable  lighting controllers that can be retrofitted to a range of LED bulb types. These include E14, GU10, A19, PAR20/30/38, MR16 and AR111.

The TPS92075 is available in a 6-pin TSOT package and 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.

Its implementation of an input current control method is designed for use with electronic transformers.
