MCP1632 Single-Cell Li-Ion battery charger demo boards were developed to help engineers reduce product design cycle time and have an optimum platform to evaluate the performance of these devices. MCP1632 provides all the analogue functions necessary to implement a stand-alone switch-mode power converter. When combined with an external microcontroller, the MCP1632 can be used to implement different intelligent converters like those necessary for battery chargers. The power train of this application uses the Single-Ended Primary Inductor Converter (SEPIC) topology. This topology offers buck-boost functionality and also has non-pulsating input current.
