Microchip Boost Converter for MCP16251, MCP1640B

MCP16251 and MCP1640B Synchronous Boost Converters Evaluation Board

The Evaluation Board for the MCP16251 and MCP1640B Synchronous Boost Converters is used to demonstrate Microchip Technology’s products:
MCP16251, Low Quiescent Current, PFM/PWM Synchronous Boost Regulator with True Output Disconnect and
MCP1640B, 0.65V Start-up Synchronous Boost Regulator with True Output Disconnect.
This board demonstrates the MCP16251/MCP1640B in two boost-converter applications with multiple output voltages. It can be used to evaluate both package options (SOT-23-6 and 2x3mm (T)DFN8). The MCP16251 and MCP1640B Synchronous Boost Converters Evaluation Board was developed to help engineers reduce the product design cycle time.
Three common output voltages can be selected: 2.0V, 3.3V and 5.0V. The output voltage can be changed with a mini-dip switch that changes the external resistor divider. A switch connected to the EN pin is used to enable and disable the converters. When enabled, the MCP16251/MCP1640B will regulate the output voltage; when disabled, the MCP16251/MCP1640B disconnects the path from input to output for “true-disconnect”.
