ARD00598: 5V @ 200mA, 4.25 ~ 5.25V in, Flyback

Summary

The MCP1661 Flyback Converter Reference Design provides an example of a galvanically isolated power supply. The board is used to evaluate and demonstrate Microchip Technology's MCP1661 in the following topology: - 5V output Isolated Flyback Converter application supplied from 5V typical input voltage.

It is used to evaluate the 5-Lead SOT-23 package. By changing the LDO, a lower/higher output voltage than 5V will be obtained, but with different capabilities regarding maximum output current and efficiency.
