Dallas—Texas Instruments' TPS65920, TPS65930, and TPS65950 power management and signal chain companion chips support all system power requirements of an OMAP35x processor-based design.
The TPS65950, which supports up to 14 voltage rails, includes 3-MHz DC/DC converters and low-noise LDOs, dual audio codec and drivers, monitor and control circuitry, battery charger, LED driver, 10-bit, 3-input a-d converter, vibra and keypad functionality, high-speed USB transceiver with integrated 5-volt power supply, and an I2 C communications interface—all in a 7-by-7 mm BGA package. The TPS65920 and TPS65930 devices, which offer a subset of features of the TPS65950, come in a 10-by-10 mm package and support up to eight voltage rails. The TPS659xx devices' I2 C interface enables the company's SmartReflex power management technologies, resulting in additional power savings.
Optimized power management
The SmartReflex technologies use deep sub-micron process geometries to significantly reduce chip-level current leakage in an OMAP35x processor. The technologies incorporate a 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. SmartReflex 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.
