Building on its power management portfolio targeting embedded processor designs, Texas Instruments Inc. introduces three fully integrated power management and signal chain companion chips to support all system power requirements of an OMAP35x processor-based design. Combining leading power management circuits with TI's low-power embedded processors results in optimized power and performance, leading to longer battery life and system run-time, according to the company.

The TPS65920, TPS65930 and TPS65950 devices reduce board space and efficiently manage system power and control for an OMAP35x processor. The TPS65950 supports up to 14 channels of power management conversion. In addition to integrated 3MHz DC/DC converters and low-noise LDOs, it includes a dual audio codec and drivers, monitor and control features, a battery charger, an LED driver, a 10bit, 3-input ADC vibra and keypad functionality, a high-speed USB transceiver with integrated 5V power supply and an I? communications interfaceall in a 7mm x 7mm BGA package. The TPS65920 and TPS65930 devices, which offer a subset of features of the TPS65950, come in a 10mm x 10mm package and support up to 8V rails.

The new power companion devices add to the company's growing number of single- and multiple-output voltage regulators that meet the needs of OMAP35x processors, says TI. In addition to its TPS659xx family, TI has shipped millions of its tiny, single-output TPS6235x family of 3MHz DC/DC converters and its multi-output TPS65023 converter, which provide increased flexibility in system optimization for OMAP35x designers.

The TPS659xx, TPS65023 and TPS6235x devices use a dedicated I? communications interface to enable TI's SmartReflex power and performance management technologies.

The TPS65920, TPS65930 and TPS65950 are currently sampling with volume production planned for Q4. Suggested resale price for the TPS65920 is $6.10, TPS65930 is $8.25 and TPS65950 $12.40, all in 1,000-piece quantities. The TPS65023 and TPS6235x devices are available in volume production from TI and its authorized distributors. Suggested resale pricing for the TPS65023 is $3.30 and TPS6235x is $1.55 in 1,000-piece quantities.
