MCP1663 9V/12V/24V Output Boost Regulator Evaluation Board
MCP1663 9V/12V/24V Output Boost Regulator Evaluation Board ( ADM00664 )

The MCP1663 Evaluation Board is used to evaluate and demonstrate Microchip Technology’s MCP1663 step-up switching regulator. This board comes with two distinct applications. The 1st circuit can be used to evaluate the MCP1663 in the typical boost configuration 9V/12V selectable output. The board also provides an example of how a higher input voltage application can be implemented.
