TI Expands Power Management Portfolio For OMAP35x Processor-Based Designs
Texas Instruments Inc. (TI) introduced 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 is said to result in optimized power and performance, leading to longer battery life and system run-time.
The TPS65920, TPS65930 and TPS65950 devices are said to 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 3-MHz 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 10-bit, 3-input analog-to-digital converter, vibra and keypad functionality, a high-speed USB transceiver with integrated 5V power supply and an I²C communications interface – all in a 7 x 7mm BGA package. The TPS65920 and TPS65930 devices, which offer a subset of features of the TPS65950, come in a 10 x 10mm package and support up to 8 voltage rails. The TPS659xx, TPS65023 and TPS6235x devices use a dedicated I²C communications interface to enable TI’s SmartReflex™ power and performance management technologies.
TI’s SmartReflex technologies leverage TI’s deep sub-micron process geometries to significantly reduce chip-level current leakage in an OMAP35x processor. The technologies are said to incorporate a broad range of intelligent and adaptive hardware and software features that dynamically control voltage, frequency and power based on device activity, modes of operation, and process and temperature variation.
SmartReflex technologies coordinate the power consumption and performance of all major system components, including multiple processing cores, hardware accelerators, functional blocks and peripherals. A library of power management cells enables a granular approach to system partitioning of the portable device’s power domains. Finally, SmartReflex technologies provide an open software framework that enables intelligent coordination among lower-level hardware technologies and compatibility with OS-based and third-party power management software.
Introduced in February, the OMAP35x devices extend the company’s wireless handset technology to mainstream consumers reaching new markets, such as consumer, embedded and medical. Based on the ARM® Cortex™-A8 processor, the OMAP35x processors feature combinations of a 2D/3D graphics engine, video accelerators and ™S320C64x+™ digital signal processor (DSP) core to provide customers with the industry’s best combination of integrated multi-core processing capabilities in a single chip.
The OMAP35x generation of devices consists of four distinct single-chip processors: OMAP3503, OMAP3515, OMAP2525 and OMAP3530. In addition, TI compliments these devices with low-power audio offerings, including codecs, speaker amplifiers and headphone amplifiers.
The TPS65920, TPS65930 and TPS65950 are currently sampling with volume production planned for the fourth quarter. Suggested resale price for the TPS65920 is $6.10, TPS65930 is $8.25 and TPS65950 $12.40 – all in 1,000-piece quantities. Suggested resale pricing for the TPS65023 is $3.30 and TPS6235x is $1.55 in 1,000-piece quantities.
