TI intros industry's first dual mode off-line controller for non-dimmable LED lighting

DALLAS, USA: Texas Instruments Inc. (TI) introduced a new off-line primary side sensing controller to its portfolio of non-dimming LED drivers. The new TPS92310 AC/DC constant current driver with power factor correction (PFC) reduces cost and shrinks-to-fit in high-power LED retrofit bulbs, including A19, PAR30/38 and GU10.

The TPS92310 is the first in a family of primary side, regulated controllers with PFC. In May, TI will offer the TPS92311 with similar features and an integrated, 600V power FET with avalanche energy capability, further reducing solution size and component count.

The TPS92310 and TPS92311 join TI's portfolio of off-line LED lighting controllers that include the National LM3445, the industry's first TRIAC dimmable LED driver with both full-range and flicker-free dimming.

The TPS92310 is available in volume now from TI and its authorized distributors. Offered in a 10-pin MSOP package, the suggested retail price is $0.49 in 1,000-unit quantities.
