Press Release Summary:
Featuring primary side sensing, Model TPS92310 shrinks-to-fit LED retrofit bulbs, including A19, PAR30/38, and GU10. Constant current driver features AC input voltage that supports all common line voltages. Adaptive constant on-time mode provides inherent PFC with no external components, while peak current control mode delivers low LED current ripple to minimize stroboscopic effects. With Zero-Current Detection, Critical-Conduction-Mode provides valley switching for optimized power conversion.
Original Press Release:
TI Introduces Industry's First Dual Mode Off-Line Controller for Non-Dimmable LED Lighting
Constant current driver with primary side sensing and power factor correction enables cost-effective, small-format retrofit light bulbs
DALLAS, -- Texas Instruments Incorporated (TI) (NASDAQ: TXN) today 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. For more information, samples and an evaluation board, visit www.ti.com/tps92310-pr.
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.

Key features and benefits of the TPS92310 LED driver
-- Adaptive constant on-time (COT) provides inherent power factor correction with no external components. PFC reduces the EMI signature to ensure regulatory approval.
-- Peak current control provides low LED current ripple to minimize stroboscopic effects.
Availability, packaging and pricing
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.
