constant current drivers provide high performance dimming performance

DALLAS, Oct. 4, 2011 / PRNewswire / - The strategies in the light of Europe conference, Texas Instruments Incorporated (TI) (NYSE: TXN) today introduced two highly integrated, adjustable phase AC / DC LED pilot lights, and LM3448 TPS92070 for use in residential solid state lighting, architectural, commercial and industrial, such as adaptive light bulbs, ballasts, LED downlights, lights and other lights . For more information and examples, see:. Www.ti.com/lm3448-pr and www.ti.com/tps92070-pr

it shows its TPS92070 LM3448 and strategies in the light of Europe (booth # 222, # 224) in Milan, Italy, October 4-6. Strategies for light is one of the events that led to global industries and LED lighting.
• National LM3448
• The adaptation time constant of AC / DC LED constant current regulator includes a MOSFET 600 V and is optimized for 2-W to 8 W-adjustable driver's LED lighting. The TPS92070 flyback AC / DC constant current regulator LED driver is optimized for 6 W to 20 W-adjustable driver's LED lighting. Both products have a thermal shutdown, VCC under-voltage lockout threshold, the cycle by cycle peak current and open LED protection.

Key Features and Benefits of the LM3448

• Designed for integration of form factors requiring LED light low component count and high performance, Dimmable LED drivers.

decoder includes a phase angle dimming compatible with TRIAC edge and end edge electronic controllers, allowing the full range of dimming LED. MOSFET RDSON

600 V

integrated protection against avalanches, high and low tension, reduces design complexity, while improving the efficiency of the LED driver.

solutions can be used in both isolated and non isolated on the basis of the topology of the money, money, or flyback pulse, using either active or passive (valley fill) the factor correction (PFC) circuits.

• Key features and benefits of TPS92070
• Advanced
  TRIAC dimmer circuit management with precise steering angle controller decodes and produces a good LED current profile exponential effective performance and provide uniform regulation of the LED light output.
  Optimized for Valley Switching and LED strict regulations (less than five percent accuracy conductor of the orchestra) in the regulation of depth.
• innovative amplifiers eliminates optocoupler and secondary reactions of errors in the design of the insulation, reducing the size and cost while improving security and reliability.

solutions can be used in both isolated and non isolated flyback topology based on the offers designers the flexibility to optimize the selection of external components, based on the requirements of size, cost and regulatory requirements.

detects the presence of a triac on and off external PFC (or valley fill or asset) to improve the performance of mitigation.

To simplify AC / DC LED driver design, TI offers an online tool that provides a navigation solution for driving LEDs in line with the specifications of the designer, such as the AC input voltage, device type, insulation and regulatory requirements. The recommended solution is supplied with the design of materials such as sheets and application notes, evaluation boards. Try the tool of AC / DC LED driver line navigation.

TPS92070

The LM3448 and join the IT portfolio of the pilot phase with adjustable LED LM3450 National with power factor correction of attenuation and phase decoding, the National LM3445, the first in Industry adjustable LED driver IC with two full-range flicker-free regulations, and the TPS92210, a natural conductor LED lighting PFC MOSFET cascode.
