DALLAS, July 25, 2011 /PRNewswire/ -- Texas Instruments
Incorporated (TI) (NYSE: TXN) today introduced a 3-MHz, 100-mA
synchronous step-down DC/DC converter, which integrates a bypass
switch and a unique DCS-Control technology. The new device extends
battery run-time by 20 percent in low-power wireless and MSP430™
MCU-based applications, when compared to competing solutions. The
high-performance device has an operating current of only 25 uA and
supports many low-power applications, such as Bluetooth®
low-energy systems, metering and building technologies, mobile
phones, consumer electronics, medical and human interface
devices.
The TPS62730 achieves 95-percent conversion efficiency and
reduces current consumption drawn from the battery in transmit and
receive modes. The device's ultra-low power bypass switch only
consumes 30 nA of current for sleep and low power modes. The
TPS62730 converter also generates less than 15 mVpp typical output
voltage ripple, providing low noise to low-power RF applications,
such as those powered by TI's 2.4-GHz CC2540 and CC430
system-on-chip (SOC) solutions. To order samples and an evaluation
module or to download the datasheet and SwitcherPro™ design tool
and PSpice® and TINA-TI™ models of the TPS62730, visit:

DCS-Control technology
DCS-Control ™ technology is an advanced regulation topology that
combines the advantages of hysteretic and voltage mode control
within a single device, enabling excellent AC line and transient
load regulation. The feature provides a seamless transition between
high-load and light-load (power save) operation. An additional
voltage feedback loop also ensures DC accuracy. DCS-Control
technology alleviates the need to research external filtering
components, thus reducing associated space and cost.
