TI introduces ultra-small boost power module for smartphones and tablets

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. It is able to extend 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.
