DOCUMENT LAYOUT
This document describes how to use the MCP1640 12V/50 mA Two Cells Input Boost
Converter Reference Design as a development tool to evaluate the MCP1640 device’s
capability to boost low voltages to a high output value, using a single inductor. The
manual layout is as follows:
? Chapter 1. “Product Overview” – Important information about the MCP1640
Input Boost Converter.
? Chapter 2. “Installation and Operation” – Includes instructions on how to get
started with the MCP1640 Input Boost Converter and a description of the User ’s
Guide.
? Appendix A. “Schematic and Layouts” – Shows the schematic and layout
diagrams for the MCP1640 Input Boost Converter.
? Appendix B. “Bill of Materials” – Lists the parts used to build the MCP1640
Input Boost Converter.
