Texas Instruments Inc. Introduces 450-V Linear Controller Simplifies Offline Led Lighting Design
Sep 30 14
Texas Instruments introduced a 450-V linear controller that simplifies current regulation of high-voltage LED strings. The TPS92410 controller integrates a multiplier and tunable phase dimmer detection, as well as analog dimming inputs and drive circuit protection functions to ease design of downlights, fixtures and lamps powered from an offline AC or conventional DC power source. The TPS92410 operates over a wide 9.5-V to 450-V input voltage range and functions as a standalone high-voltage LED string current regulator or pairs with TI's TPS92411 floating switch to provide power in mains AC linear direct drive applications. Together, the TPS92410 and TPS92411 feature driver and LED circuit protection while providing an inductor-free, low LED current ripple lighting solution. The TPS92410 includes an analog dimming input pin with LED shutoff to provide easy light intensity control in intelligent, MCU-based light fixtures using the ultra-low-power MSP430F5172 microcontroller or SimpleLink(TM) ZigBee(R) CC2530 wireless MCU. Key features and benefits of TPS92410 were AC and DC applications, Under-voltage lockout, MOSFET over-voltage protection and thermal foldback prevent driver and LED damage during fault conditions. AC applications with TPS92411; Compatible with legacy TRIAC and reverse phase dimmers in AC mains powered LED lighting applications. On-chip, internal multiplier produces very high power factor correction at greater than 0.95 with within plus or minus 3% line regulation. Available now in volume from TI and its authorized distributors, the TPS92410 is offered in a 13-pin SOIC package and is priced at USD 0.65 each in 1,000-unit quantities. LED lighting tools and support: The 120-V TPS92410EVM-001 and 230-V TPS92410EVM-002 light engine evaluation modules are available at USD 99.00 each.

Texas Instruments Inc. to Pay $3 Million After Violating Chip Patent
Sep 26 14
Texas Instruments Inc. announced that it reportedly will have to pay $3 million in damages after a jury decided that it violated a patent owned by U.S. Ethernet Innovations. A federal jury ruled in favor of the Ethernet company, which claimed that TI infringed on its system-on-chip technology, which is used in microprocessors. The jury found that three of TI's products violated its patent and that TI 'induced infringement' on the other four claims. TI plans to appeal the ruling.
Texas Instruments Introduces Its First Transimpedance Amplifier for the 100G Optical Networking Market
Sep 22 14
Texas Instruments introduced its first transimpedance amplifier (TIA) for the 100G optical networking market. As a key component of the system, the ONET2804T brings high levels of sensitivity with negligible cross-talk penalty and low input-referred noise (IRN) to provide stable and robust communication in hot-pluggable transceivers. The newest member of TI's broad optical networking portfolio, the 100G TIA serves parallel optical interconnects in applications with data rates of up to 28 Gbps, such as optical line cards, point-to-point microwave backhauls and video over fiber. Key features and benefits of the ONET2804T: High level of sensitivity: Less than 2-uA IRN and virtually no cross talk between channels help achieve high signal integrity. Design flexibility: Using a two-wire I2C interface, designers can optimize their systems to drive high performance at low power consumption. Easy system integration: The new TIA's 750-um channel pitch enables designers to wire bond directly to a photodiode, which reduces system complexity. The ONET2804T four-channel 28-Gbps TIA adds a new dimension to TI's popular line of optical networking products. In addition to TIAs, the portfolio features various types of laser drivers and limiting amplifiers to build optical networking systems. Availability, packaging and pricing: The ONET2804T is available in a 750-um channel-pitch bare die. Suggested retail pricing in 1,000-unit quantities starts at $45.00.
Texas Instruments Introduces Seven SIMPLE SWITCHER Regulators
Sep 19 14
Texas Instruments (TI) introduced seven SIMPLE SWITCHER regulators that simplify wide V(IN) synchronous power supply design and help engineers create energy-efficient, electromagnetic interference (EMI) compliant products. The easy-to-use LM43600/1/2/3 and LM46000/1/2 DC/DC converters feature an input voltage range of up to 60 V for high reliability in rugged systems, and 27 micro amps of standby current that minimizes power consumption at light load. The unique synchronous power stage architecture reduces radiated emissions for EMC compliance in a variety of industrial, automotive and communications applications. The LM43600, LM43601, LM43602 and LM43603 synchronous regulators support an input voltage range from 3.5 V to 36 V and generate output currents of up to 0.5 A, 1 A, 2 A and 3 A, respectively. The LM46000, LM46001 and LM46002 support an input of 3.5 V to 60 V and output currents of up to 0.5 A, 1 A and 2 A. The converters integrate compensation, control features and MOSFETs to reduce the bill of material (BOM) by up to seven components. The HTSSOP package is leveraged across the entire family, allowing pin - and footprint-compatibility, as well as scalability. The regulators are fully supported in the company's WEBENCH(®) online design tool, helping designers generate, optimize and simulate a wide V(IN) design, and then export that design to a CAD program. Read a blog on how to simplify design with SIMPLE SWITCHER products and WEBENCH tools. The company's SIMPLE SWITCHER family has been solving power design problems for 25 years. The award-winning portfolio of products includes easy-to-use power modules, regulators and controllers. Supporting input voltage ranges from 3 V to 75 V, and currents from 300 mA to 5A, the products are fully functional in the company's WEBENCHPower Designer, Power Architect and FPGA Power Architect design and prototyping tools. The SIMPLE SWITCHER synchronous regulators are available in volume now from TI and its authorized distributors. The LM43600/1/2/3 regulators are priced at USD 1.50, USD 1.60, USD 1.75 and USD 1.85, respectively, in 1,000-unit quantities. The LM46000/1/2 regulators are priced at USD 1.65, USD 1.75 and USD 1.85. Automotive grade versions of the LM43602 and LM43603 will be available in early 2015.
