The Microchip Technology MCP19125 Flyback Battery Charger Evaluation Board demonstrates how the MCP19125 device operates in a battery charging application utilizing a synchronous flyback topology. It is configured to regulate the amount of charge current, and the type of charging, while simultaneously reading the state of the battery to change between operation modes for optimized charge profiles. Nearly all operational and control system parameters are programmable by utilizing the integrated PIC® microcontroller. MPLAB X IDE can be used in conjunction with a downloadable Graphical User Interface (GUI) to easily configure the MCP19125. Alternatively, the user can program the MCP19125 using their own firmware, tailoring it to their application. The evaluation board contains headers for ICSP™ (In-Circuit Serial Programming™) as well as I2C communication, numerous test points, and a push-button for system development.
