Overview

Smart Wireless Sensors are typically powered by Long-Life Batteries Like LiSoCl2 chemistry which are limited in current. However, these sensors require high current pulses for transmitting the gathered data wirelessly. This Reference Design provides a solution for powering the MCU with reduced current and high current pulses to the radio. These pulses are decoupled from the battery by Energy Buffering.

Features
  • Buck (MCU) and Boost (RF-PA) Rail
  • Load Decoupling with Energy Buffering
  • Ultra Low Iq
  • Longer Battery Runtime by VDD Down Conversion

A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
