TI chip manages power of ARM Cortex processors

TI TPS65090Texas Instruments has introduced its first front-end power management device for battery-powered applications based on ARM Cortex-A9 and -A15 processors.

The TPS65090 chip integrates a 4A switching charger, three 5A DC-DC step-down converters, seven load switches, two always-on LDOs and a 10-channel analogue-to-digital converter (ADC).

It achieves up to 95% efficiency across 8V to 12V output voltages for two to three cells in series.

Portable electronics

The device is designed to carry out power management functions to improve efficiency and so extend battery run-time in tablets and other portable electronics by 20%, claimed the supplier.

The TPS65090 is available in a multi-row QFN package  and there is the TPS65090EVM evaluation module.
