DALLAS, Oct. 3, 2011 /PRNewswire/ -- Texas Instruments
Incorporated (TI) (NYSE: TXN) today introduced two 20-V step-down
voltage regulators with PMBus digital interface and adaptive
voltage scaling capability for non-isolated point-of-load designs.
Together with the National system power protection and management
products, TI provides the design engineer with complete single-,
dual- and multi-rail, multi-phase PMBus solutions -- allowing
telecom and server designers to intelligently monitor, protect and
manage the state of health of their power systems.
Flexible step-down controllers
TI's 2-MHz TPS40400 single-channel controller with a 3-V to 20-V
input range and the new 1.2-MHz TPS40422 dual-channel or
multi-phase controller with 4.5-V to 20-V input voltage range
combine high-performance analog voltage regulation with digital
control to achieve greater than 90-percent efficiency, tight output
voltage accuracy and design flexibility. The devices' unique
adaptive voltage scaling capability saves up to 25-percent more
power than previous solutions, and eliminates the need for up to 12
external components. The controllers achieve even greater power
efficiency when paired with TI's NexFET™ power MOSFETs, such as the
CSD87350Q5D.
"Telecom, cloud computing data centers and mobile internet
infrastructure applications require high-performance, low-risk
digital power management solutions," said Niklas Fallgren, vice president and general
manager of OEM Embedded Power at GE Energy. "TI's integrated
digital power controllers help our DLynx™ point-of-load modules
deliver real-time diagnostics and monitoring with adaptive voltage
scaling, while ensuring PMBus interoperability."
Designers configure the TPS40400 or TPS40422's parameters to
monitor and control the power system using TI's easy-to-use
graphical user interface software tool. In addition, TI's
SwitcherPro™ tool makes it easy to develop internally and
externally compensated designs in less than one minute.
System power protection and management
The TPS40400 and TPS40422 can be combined with the National 17-V
LM25066 system power and hot-swap protection IC as a complete
PMBus-compliant solution for 12-V systems with input protection and
power conversion. The LM25066 continuously supplies the system
management controller with real-time, accurate power measurement
including voltage, current, temperature and fault data for each
blade subsystem in a telecom or server application – enabling
increased reliability. For those 48-V systems that generate a 12-V
intermediate bus, the National +/- 48-V LM5066 and LM5064 system
power and protection circuits accurately measure, protect and
control the electrical operating conditions.
Do more with TI Digital Power
TPS40400 and TPS40422 analog PMBus controllers and the National
system protection ICs extend TI's portfolio of digital power
products that meet any non-isolated or isolated power design
requirement. UCD9K and UCD3K digital power controllers and UCD7K
drivers provide built-in hardware features to make implementation
of power topologies easier, faster and more accurate, while
providing a high degree of configurability. TI's fully programmable
TMS320F28x Piccolo™ and Delfino™ 32-bit microcontrollers provide
intelligent digital power peripherals, flexible software
programmability and real-time control performance for power
supplies. See: www.ti.com/digitalpower.
