TPS81256 Ultra-Small Boost Power Module from TI for Portable Electronics Devices

Smallest integrated boost converter

Smartphone and tablet designers continue to require smaller point-of-load converters, while maintaining long battery run-time with high power conversion efficiency. The 4-MHz, 600-mA TPS81256 module supports a 5-V output with a power density of 400 mW/mm3. The device extends battery life by reducing the supply current to 43 uA during light load operation. The TPS81256 also achieves power efficiency of greater than 90 percent from an input voltage of 2.5 V to 5.5 V, enabling it to efficiently manage 3 W over a full Li-Ion battery voltage range.



Key features and benefits of the TPS81256:

•Smallest solution size: Achieves a solution less than 9 mm2 and profile less than 1-mm tall, providing a power density of 400 mW/mm3.

•Simplifies design: High integration, including passives and capacitors, significantly reduces hardware design and layout effort.

•High performance: Up to 91-percent peak efficiency, and high efficiency over a wide load range.



Broadest range of point-of-load solutions

TI offers the broadest range of power management integrated circuits (ICs) and modules for point-of-load designs, including step-up and step-down converters for portable and line-powered systems. These range from ultra-low power DC/DC converters with and without integrated FETs to fully integrated power solutions, such as the TPS81K, TPS82K, TPS84K and SIMPLE SWITCHER® modules.



Availability and pricing

The TPS81256 is available now in a 9-bump, 2.6-mm x 2.9-mm x 1-mm MicroSiP package suited for automated assembly by standard surface mount equipment, and is priced at $1.70 in quantities of 1,000. Designers can order the new TPS81256EVM-121 evaluation module to help speed time to market.
