The MCP1642B Two-Cells to USB Power Evaluation Board is used to evaluate and demonstrate Microchip Technology’s MCP1642B Switching Boost Regulator. This board demonstrates the MCP1642B capabilities in a boost-converter application supplied from two AA batteries or from an external voltage source. A USB cable can be connected to the output of MCP1642B Two-Cells to USB Power Evaluation Board and used to provide power to portable electronic devices when necessary. It can be used to evaluate the MSOP-8 package. The MCP1642B Two-Cells to USB Power Evaluation Board was developed to help engineers reduce the product design cycle time. On the MCP1642B Two-Cells to USB Power Evaluation Board, the output voltage has the value of 5.0V (the fixed value MCP1642B-50 device is used), resulting in a simple and compact application. The footprints for RT and RB (resistor divider connected to the FB pin) are not populated and will only be used if MCP1642B-ADJ, the adjustable option, will be tested. An enable (EN Switch selection) is used to enable and disable the converter. When enabled, the MCP1642B will regulate the output voltage; when disabled, the MCP1642B will disconnect the path from input to output for “true-disconnect”
