DALLAS, Nov. 27, 2012

DALLAS, Nov. 27, 2012 /PRNewswire/ -- Texas Instruments Incorporated (TI)
(NASDAQ: TXN) today introduced two 3.5-A step-down DC/DC converters with an
integrated MOSFET and industry-leading reference accuracy of one percent. The
SWIFT™ 60-V TPS54360 and 42-V TPS54340 buck regulators operate over a wide
input voltage range and the industry's widest temperature range for
high-performance industrial, consumer, computing, communication and automotive
applications. Using these new products together with TI's WEBENCH^® online
design tool can simplify and speed the design process. For more information
and samples, visit www.ti.com/pmp-tps54360-pr-en. Watch a video demonstration
at www.ti.com/pmp-tps54360-prv-en.

The TPS54360 and TPS54340 join TI's family of Eco-Mode™ SWIFT DC/DC converters
that operate over a wide input range with low operating and shutdown quiescent
current. The family also includes the 0.5-A, 42-V TPS54040A and 1.5A, 60-V
TPS54160A that feature precision enable threshold for adjustable under voltage
lockout. For more information on all of TI's SWIFT converters, visit

Key features and benefits of the TPS54360 and TPS54340 DC/DC converters

  oWide input range from 4.5 V to 60 V (TPS54360) or 42 V (TPS54340) offers
    robust input voltage protection.
  oCurrent mode control allows simple external compensation and flexible
    component selection.
  oIntegrated 92-mOhm high-side MOSFET provides high efficiency at high
    currents.
  oIndustry-leading one-percent reference accuracy from -40 degrees C to 150
    degrees C better regulates output voltages over all operating conditions.
  oLow dropout operating mode approaching 100 percent duty
    cycleminimizesinput to output voltage drop.

Availability, packaging and pricing
The TPS54360 and TPS54340 DC/DC converters are available in volume now from TI
and its authorized distributors. Offered in an 8-pin SOIC PowerPAD™ package,
the TPS54360 is priced at US$2.10 and the TPS54340 is US$1.75 in 1,000-unit
quantities. The PowerPAD package lowers the thermal resistance to extend the
temperature operation range and improve long-term reliability.
