The innovative front-end PMU integrates a 4-A switching PowerPath charger, three 5-A DC/DC step-down converters, seven load switches, two always-on LDOs and a 10-channel analog-to-digital converter.
Key features and benefits of the TPS65090:
•20-percent increased battery run-time: Up to 95-percent efficiency across 8-V to12-V output voltages for two to three cells in series.
•High integration, smallest solution size: The device integrates 15 functions into one front-end circuit to reduce the bill of materials and achieve a 60-percent smaller total solution than using discrete ICs.
•Faster charging: Integrated 4-A, multi-cell switching charger cuts charging time in half.
•Advanced power control: The power switches allow independent control of each major subsystem, and the 10-bit ADC allows easy, accurate monitoring of power consumption.
Availability, packaging and pricing
The TPS65090 is available today in multi-row QFN packaging for a suggested retail price of USD$4.95 in 1,000-unit quantities. Designers can order the TPS65090EVM evaluation module to quickly evaluate their designs and speed time-to-market.
