2.0 Design Features
This document provides a reference design for a universal input, 5V 600mA isolated yback switched-mode power
supply. For this design the iW1810-00 is used. This document contains the complete specication of the power supply, a
detailed circuit diagram, an entire bill of materials required to build the power supply, a drawing of the power transformer,
and test data of the most important performance.
