1 Setup and Configuration

The Building Block Solutions – Switchers Board is fully assembled and tested to evaluate and demonstrate the features of the MCP16251, MCP16311, MCP16411, MCP1663, MCP1664, and MCP16331 monolithic switching regulators. For proper evaluation, this board requires an external laboratory power supply and load (including LEDs).
