The objective of this design is to provide a turn-key solution able to power the electronics of isolated loop powered 4 to 20 mA transmitters or other low power applications with limited input current budget. It addresses the key requirements of such applications like operating over wide input voltage range, providing isolated and no-isolated noise-free outputs and offering a complete set of protection features. Multiple test points on the board, a dual layer - single side populated construction and a comprehensive documentation enable easy testing, modification and optimization by the user.
