Highly integrated 600-mA MicroSiP™ power module achieves 9-mm2 solution size, extends battery life
Texas Instruments Incorporated introduced the industry's smallest integrated step-up (boost) DC/DC power module for smartphones, tablets and other portable electronics. The new, efficient TPS81256 MicroSiP™ converter integrates the inductor and input/output capacitors to achieve a solution less than 9-mm2 and sub-1 mm height, simplifying design and saving up to 50-percent more board space versus competing solutions.
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:
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 × 2.9-mm × 1-mm MicroSiP package suited for automated assembly by standard surface mount equipment, and is priced at $1.70 in quantities of 1,000.
