DALLAS, March 5, 2013

DALLAS, March 5, 2013 /PRNewswire/ --Texas Instruments Incorporated (TI)
(NASDAQ: TXN) today introduced three new 48-V synchronous buck regulators with
integrated high-side and low-side MOSFETs for single- and multi-output power
supplies. The 650-mA LM25017, 300-mA LM25018 and 100-mA LM25019 Fly-Buck™
converters feature constant on-time (COT) control architecture that reduces
board space by up to 40 percent when compared with traditional designs that
require multiple DC-DC converters. Used in conjunction with TI's award-winning
WEBENCH® online design tool, the Fly-Buck converters simplify and speed
high-voltage DC/DC designs in industrial and automotive systems. For more
information, samples and evaluation modules, visit www.ti.com/lm25017-pr.

The LM25017, LM25018 and LM25019 enable non-isolated voltage regulators and
multi-output solutions from input voltages as high as 48 V. Pin-compatible LLP
and PSOP packaging offers a scalable solution that covers a wide range of
power requirements. Each Fly-Buck converter can be configured to provide
positive and negative voltage rails, or isolated multiple outputs with
excellent cross-regulation.

The Fly-Buck converters are pin-to-pin compatible with TI's 100-V, 600-mA
LM5017, 300-mA LM5018 and 100-mA LM5019 wide input voltage range regulator
family. For designs that have a 3.3-V or 5-V input source and require an
isolated voltage up to 2 W, TI offers the TPS55010 Fly-Buck converter with
high efficiency and primary-side regulation. For more information on all of
TI's high-voltage point-of-load products, visit www.ti.com/pol-pr.

Key features and benefits of the Fly-Buck converters

  oFly-Buck converters simplify design of a variety of power supplies,
    including those with isolated multi-output, or positive and negative
    voltage rails.
  oCOT control architecture provides excellent load transient response and
    eliminates loop compensation, lowering cost and simplifying design.
  oIntegrated high-side and low-side N-Channel MOSFETs improve efficiency and
    eliminate external Schottky diode.

Availability, packaging and pricing
The new Fly-Buck converters are available in volume now from TI and its
authorized distributors. Offered in thermally-enhanced 8-pin LLP and PSOP
packages, the LM25017 is priced at US$1.25, the LM25018 is US$1.12 and the
LM25018 is US$1.00 in 1,000-unit quantities. AECQ-100 qualified versions will
be available in May 2013.
