TI PMU Solutions

The TPS65K family of Power Management Units (PMUs) – also called PMICs – offers complete power solutions for portable applications. TI offers front-end PMUs (charger plus additional portable functions), processor PMUs powering the latest ARM Cortex A9 and A15 processors, and general-purpuse PMUs for industrial based applications.

PMUs integrate high-efficiency DC/DC converters and LDOs for the processor core, I/O, memory and other voltages. Also available are integrated functions such as a battery charger (linear or switching), flash and WLED backlighting, ADCs, touch-screen controller, audio codec and a USB 2.0 PHY. TI’s SmartReflex™ technology and dynamic voltage scaling (DVS) can significantly extend battery life by adjusting the output voltages to match the required performance.
