MCP19111 Battery Charger Evaluation Board

The MCP19111 is a highly integrated, mixed signal, analog pulse-width modulation (PWM) current mode controller with an integrated microcontroller core for synchronous DC/DC step-down applications. Since the MCP19111 uses traditional analog control circuitry to regulate the output of the DC/DC converter, the integration of the PIC microcontroller mid-range core is used to provide complete customization of device operating parameters, start-up and shut down profiles, protection levels and fault handling procedures.
