POWER SUPPLY FOR INDUSTRIAL PROCESS FIELD DEVICE

摘要

A wireless industrial process field device for use in controlling or monitoring a process variable of an industrial process includes a process interface element configured to sense or control the process variable of the industrial process. Process device circuitry includes a process interface circuit configured to measure or control the process variable of the industrial process with the process interface element. Wireless communication circuitry is configured for wireless communication. Power supply circuitry is configured to provide power to the process device circuitry from a power storage element at an output voltage. A low drop out (LDO) voltage regulator is configured to reduce the output voltage. A boost converter is configured to increase the output voltage.
