MCP19111 - Hybrid Controllers - Microchip
MCP19111 is a mid-voltage (4.5 - 32 V) analog-based Pulse Width Modulation (PWM) controller family with an integrated 8-Bit PIC® Microcontroller. This unique product combines the performance of a high-speed analog solution, including high-efficiency and fast transient response, with the configurability and communication interface of a digital solution. Combining these solution types creates a new family of devices that maximizes the strengths of each technology to create a more cost-effective, configurable, high-performance power conversion solution. The MCP1911X family, when combined with Microchip's MCP87XXX MOSFETs, or any low Figure-of-Merit (FOM) MOSFET, produce high-efficiency (> 96%) DC/DC power-conversion solutions.
Figure-of-Merit devices focus on minimizing both on-state resistance (Rdson) and gate charge (Qg). They are focused on maximizing power conversion performance, making them ideal for switched-mode power supply applications.
MCP19111 Target Applications
MCP19111 Power Supply Evaluation board (ADM00397)
The MCP19111 Evaluation 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 Graphical User Interface (GUI) plug-in to easily configure the MCP19111. Alternatively, you can program the MCP19111 using your own firmware, tailoring it to your application. The evaluation board contains headers for ICSP™ (In-Circuit Serial Programming™) 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.
