Abstract
A process transmitter suitable for coupling to a process loop. The process transmitter includes a power regulator adapted to receive a power signal on the process loop and to provide a first signal having a first voltage. Digital components of the process transmitter are electrically coupled to the power regulator to receive power from the first signal. A step-up converter is electrically coupled to the power regulator and receives the first signal. The step-up converter outputs a second signal having a second voltage larger than the first voltage. Analog components of the process transmitter are electrically coupled to the step-up converter to receive power from the second signal.
