TI adds 20-percent run-time to ultra-low power wireless applications with 3-MHz, 100-mA step-down DC/DC converter
Texas Instruments 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.
