ADM00397

The ADM00397 is an Evaluation Board for MCP19111, a digitally-enhanced PWM controller. It combines a pure-analogue PWM controller with a supervisory microcontroller making it a fast and configurable power conversion solution. The MCP19111 is ideal for standard power conversion, LED drivers and battery charging applications. The board demonstrates how the MCP19111 device operates in a synchronous buck topology over a wide input voltage and load range. Nearly all operational and control system parameters are programmable by utilizing the integrated PIC microcontroller core. MPLAB X IDE can be used in conjunction with a GUI plug-in to easily configure the MCP19111. Alternatively, the user can program the MCP19111 using their own firmware, tailoring it to their application. The evaluation board contains headers for ICSP™ as well as I²C communication, pull-up and pull-down resistor pads and test point pads on each GPIO pin and two push buttons for system development.
