2.2 GETTING STARTED
The MCP1663 Mini-Module SEPIC Converter Evaluation Board is fully assembled and
tested to evaluate the MCP1663 product and demonstrate its capabilities. This board
requires the use of external laboratory power supplies and load.
The mini-module’s performance was tested using a motherboard which includes a
DDPAK footprint, as shown in
Figure 2-3 . All measurements presented in this docu-
ment were performed by utilizing this motherboard.
