TI chip manages power of ARM Cortex 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.
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.
