DALLAS, April 7, 2011 /PRNewswire/ -- Texas Instruments
Incorporated (TI) (NYSE: TXN) expanded its industry-leading power
management portfolio with two new step-down regulators with wide
input voltages and high-voltage protection. The new 100-V LDO and
60-V DC/DC controller can withstand high-voltage transients, while
maintaining high efficiency -- providing peace of mind to designers
of low- to mid-current, high-voltage telecom and industrial
designs, such as motor control, HVAC relay, smart meters and
automotive after-market applications.
Highest voltage LDO
The TPS7A4001 50-mA LDO has the industry's widest input voltage
tolerance with an input voltage 7 V to 100 V, and achieves an
extremely fast settling time of less than 500 nanoseconds for a
50-V transient event. The device, which comes in a tiny 8-pin,
thermally enhanced 3-mm x 5-mm MSOP package, has a low quiescent
current of 25 uA and ensures output accuracy in a noisy
environment. For samples and evaluation modules visit:

Wide-input, 60-V buck controller
The TPS40170 synchronous step-down DC/DC controller offers a
high degree of performance, efficiency and reliability, including
voltage-mode control with input voltage feed-forward compensation,
while supporting input voltages from 4.5 V to 60 V and output
currents up to 12 A. The controller protects against voltage spikes
up to 62 V, offers a fast FET on-time of 75 ns and shutdown current
of 1.0 uA. The TPS40170's unique bi-directional synchronization
feature eliminates system beat and EMI noise and reduces input
capacitance by up to 50 percent, saving board space. The device
comes in a 3.5-mm x 4.5-mm QFN, and has samples and evaluation
modules available at: www.ti.com/tps40170-pr.
SWIFT™ converters with integrated FETs
In addition to the TPS40170 controller, TI provides a range of
SWIFT monolithic switchers with integrated FETs to simplify design
in lower current 60-V applications. The 2.5-A TPS54260, 1.5-A
TPS54160 and 500-mA TPS54060 converters provide up to 95 percent
efficiency to 12-, 24- and 48-V industrial and commercial designs
and GSM/GPRS modules used in smart meters, fleet management and
security systems. All three SWIFT converters are pin-compatible for
design flexibility. For more information, visit:

Managing system power requirements
TI's power management converters and controllers efficiently
manage the system power requirements in industrial applications
that use a variety of embedded processors including TI's new
MSP430AFE2xx series of metrology analog-front end (AFE)
ultra-low-power 16-bit MCUs, C2000™ real-time control MCUs,
Stellaris® ARM® Cortex™-M MCUs, C6-Integra™ DSP+ARM processors,
C6000™ high-performance DSPs and C5000™ ultra-low power DSPs.
Availability and pricing
The TPS7A4001 is available in volume now from TI in an 8-pin,
3-mm x 5-mm MSOP PowerPad™ package. Suggested resale pricing is
$1.90 in 1,000-unit quantities. The
TPS40170 controller comes in a 3.5-mm x 4.5-mm QFN with a suggested
resale price of $2.40 in 1,000-unit
quantities.
