Texas Instruments Incorporated today introduced a fully integrated, 10-A synchronous buck converter with integrated FETs that combines wide input, light load efficiency and reduced solution size to enable increased power density. The TPS51315, a 1-MHz DC/DC switcher, features D-CAP™ Mode control scheme, which allows a fast transient response while reducing the required number of external output capacitors by 32 percent compared to competing dev...

Texas Instruments has introduced a fully-integrated load switch with typical ON resistance (rON) of 5.7-mW at 3.6-V, four times lower than the nearest competitor. TI’s TPS22924C integrates at least four parts into one to simplify subsystem load management.

Texas Instruments has introduced a space-saving, 400mA step-down converter for portable designs. The 95-percent efficient converter extends battery life in mobile phones, portable navigation systems and low-power DSP and microcontroller applications. TI’s TPS62270 synchronous DC/DC converter efficiently regulates output voltages down to 0.9 V with ±1.5 percent accuracy, enabling the device to power TI’s newest C5000 DSPs, low-p...

With the February 2009 transition from analogue to digital TVs, consumer demand on energy resources is increasing. Two power management chips from Texas Instruments, a dual-phase power factor correction (PFC) controller with Natural Interleaving technology and a new SWIFT DC/DC power management converter, will help increase energy efficiency and reduce system size and cost in Digital TVs.

Texas Instruments Incorporated today introduced the industry’s first two-channel, simultaneous-sampling successive approximation (SAR) analog-to-digital converters (ADCs) with two independently controlled internal references for simplified system-level design. The 16-bit ADS8363, 14-bit ADS7263 and 12-bit ADS7223 are pin-for-pin compatible and provide twice the per-channel throughput of similar ADCs, supporting speeds up to 1 MSPS for indus...

Texas Instruments Incorporated has expanded its portfolio of general-purpose, low-power, rail-to-rail output operational amplifiers (op amps) with the introduction of new single and dual analog-to-digital converter drivers that provide the industry’s highest performance-to-power ratio. The OPAx836 op amps use 33 percent less power than similar solutions while providing more than twice the bandwidth, 15 times faster slew rate, 40 times bette...

Texas Instruments Incorporated reducing the bill of materials for wideband transmit systems with new dual, 500-MSPS digital-to-analog converters (DACs) starting at less than $10 in 1,000 unit quantities. The 12-bit DAC3162 and 10-bit DAC3152 are the smallest, least-expensive and lowest-power devices in their class and were designed for wideband transmit systems, such as wireless base stations, software defined radio, point-to-point microwave, e-b...

Texas Instruments has introduced two new PurePath DigitalT power stages. The TAS5261 provides OEMs with the industry's highest power single-chip digital amplifier power stage, capable of driving more than 300 watts (W) into a 4-ohm speaker, while the two-channel TAS5162 digital amplifier power stage can drive 200 W per channel at 6 ohms and 125 W at 8 ohms. The devices enable higher efficiency and sound quality in a variety of audio applications,...

Texas Instruments has introduced an expansion of its high-performance family of fully-differential amplifiers that drive high-speed and high-resolution analog-to-digital converters (ADC). Designed for high accuracy 3.3V to 5V data acquisition systems, the new wideband device offers rail-to-rail output and provides both low noise and the lowest distortion for demanding applications such as wireless communication, test and measurement and medical i...

Texas Instruments has introduced a new family of two- and four-channel 12- and 14-bit analog-to-digital converters (ADCs) featuring high speed, low power and high performance housed in tiny 9-mm x 9-mm packages. This pin-compatible family offers designers an easy upgrade path with a range of resolutions, speed and performance options tailored to meet the requirements of advanced communications, radar and imaging, test and measurement, medical, an...
