Designing Cost-Effective, Low Power Galvanic Isolation Solutions for Power Supplies

Published by Bourns Inc

Standard industrial interfaces such as RS-485 and RS-232 are commonly used for unidirectional and bidirectional data transfer in a range of applications that encompass everything from medical monitoring to test and measurement equipment.

This paper presents the reasons for galvanic isolation in board designs that incorporate common RS-485 or RS-232 data interfaces or for sensors that can be sensitive to ground loops. It will also provide an optimal design methodology for the implementation of a coupled inductor with high creepage and clearance for a 2 W power supply
