MCP1640 DC-DC Boost Converter Ref Design

The MCP1640 12V/50mA Two Cells Input Boost Converter Reference Design is designed to demonstrate the MCP1640 device’s high-voltage boost capability above its typical output range of 5.5V. This board boosts the low-voltage input to 12V and up to 70mA load. By changing specific resistors, a lower/higher output than 12V can be obtained. The MCP1640 Input Boost Converter was developed to help engineers reduce product design cycle time. At 2.0V input and 12V output the board is capable of a maximum of 50mA load current.
