DALLAS, Feb. 4, 2013

DALLAS, Feb. 4, 2013 /PRNewswire/ -- Texas Instruments Incorporated (TI)
(NASDAQ:TXN) today introduced the industry's first single-chip, front-end
power management unit (PMU) for battery-powered applications based on ARM
Cortex A9 and A15 processors. The TPS65090 power management integrated circuit
integrates all power management functions and maximizes power efficiency to
extend battery run-time in tablets and other portable electronics by 20
percent, simplify design, and reduce board space by 60 percent compared to a
discrete approach. To order free samples, visit: www.ti.com/tps65090-pr.

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 (ADC).

Key features and benefits of the TPS65090:

  o20-percent increased battery run-time: Up to 95-percent efficiency across
    8-V to 12-V output voltages for two to three cells in series.
  oHigh 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.
  oFaster charging: Integrated 4-A, multi-cell switching charger cuts
    charging time in half.
  oAdvanced 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.
