Microchip Evaluation Board for the MCP19122 PWM Controller

Operates over a wide input voltage and load range

The MCP19122 Evaluation Board (ADM00397) by Microchip demonstrates how the buck controller 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.

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.

Features

  • Vin range: 5V to 12V
  • Adjustable Vout range: 0.5V to 3.6V
  • Maximum output current: 30A with proper air flow
  • Programming and I2C communication headers
  • Factory programmed to produce 1.8V from 12V source
  • The factory programmed source code is available

MPLAB X IDE can be used in conjunction with a Graphical User Interface (GUI) plug-in to easily configure the MCP19122. Alternatively, the user can program the MCP19122 using their own firmware, tailoring it to their application.

MCP19122

The Microchip MCP19122 is a mid-voltage (4.5-40V) analog-based synchronous buck PWM controller 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.
