PMP9763, Smart Meter Power Management Solution with Energy Buffering Reference Design. 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
