Note the following details of the code protection feature on Microchip devices:
•
Microchip products meet the specification contained in their particular Microchip Data Sheet.
•
Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the
intended manner and under normal conditions.
•
There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our
knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data
Sheets. Most likely, the person doing so is engaged in theft of intellectual property.
•
Microchip is willing to work with the customer who is concerned about the integrity of their code.
•
Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not
mean that we are guaranteeing the product as “unbreakable.”
Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our
products. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts

Chapter 1. Product Overview
1.1
INTRODUCTION
This chapter provides an overview of the MCP19111 Evaluation Board and covers the
following topics:
• MCP19111 Short Overview
• What is the MCP19111 Evaluation Board
• MCP19111 Evaluation Board Kit Contents
1.2
MCP19111 SHORT OVERVIEW
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.
The MCP19111 is designed to efficiently operate from a single 4.5V to 32V supply. It
features integrated synchronous drivers, bootstrap device, internal linear regulator, and
4K word nonvolatile memory all in a space-saving 28-pin 5 mm X 5 mm QFN package.
After initial device configuration by using Microchip’s MPLAB X Integrated Development Environment (IDE) software, PMBus™ or I2C communication can be used by a
host to communicate with or modify the operation of the MCP19111. A subset of the
PMBus 1.1 specification commands are supported by the MCP19111.
An internal 5V rail provides power to the PIC MCU and is also present on the VDD pin.
It is recommended that a 1 µF capacitor be placed between VDD and PGND. The VDD
pin may also be directly connected to the VDR pin or connected through a low pass RC
filter. The VDS pin provides power to the internal synchronous driver.

WHAT IS THE MCP19111 EVALUATION BOARD
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 (See Section 2.1.1 “MCP19111 Features” for a full
list of programmable parameters). MPLAB X IDE can be used in conjunction with a
Graphical User Interface (GUI) plug-in to easily configure the MCP19111. For more
information regarding the GUI plug-in, refer to the “MCP19111 MPLAB® X Integrated
Development Environment Plug-in User’s Guide” (DS52113). Alternatively, the user
can program the MCP19111 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, pull-up and pull-down resistor pads and test point pads
on each GPIO pin, and two push buttons for system development. The MCP19111
Evaluation Board is also intended to demonstrate an optimized Printed Circuit Board
(PCB) layout that minimizes parasitics while increasing efficiency and power density.
Proper PCB layout is critical to achieve optimum MCP19111 operation, as well as
power train efficiency and noise minimization. MPLAB X IDE, the MCP19111 GUI
plug-in, and example firmware is available for download from the Microchip website.

MCP19111 Evaluation Board Features
The MCP19111 Evaluation Board is designed to operate within an input voltage range
of 5 to 12V, and an output voltage range of 0.5V to 3.6V. The MCP19111 is paired with
Microchip's low capacitance, low resistance MOSFETs to provide an efficient and
robust power train solution, allowing operation to be assessed at load currents of up to
20A with proper airflow. Adequate ceramic and bulk capacitors are supplied on the
input to reduce RMS ripple current and tame input voltage deviation caused by load
transients. A mix of ceramic and bulk capacitors is also provided on the output to
reduce voltage ripple and provide fast response to load transients.
The MCP19111 Evaluation Board provides the user with an example of an optimized
PCB layout which reduces parasitics and increases power density. Some features of
this board design include:
• Wide, short traces used to connect power components
• Ceramic VIN capacitors placed as close to the drain of the high-side MOSFET as
possible, and as close to the source of the low-side MOSFET as possible
• Split ground plane to decouple the digital and power ground signals
• Careful placement of current sense components to reduce PCB induced noise
DS52109A-page 14

Installation and Operation
The MCP19111 Evaluation Board also provides test points for easy access to power
train signals such as high-side gate drive, low-side gate drive and phase node. The
VOUT signal, which is fed back into the MCP19111 through resistor R26, provides a
convenient injection point for stability analysis. Eight of the MCP19111's GPIO pins are
brought out to test points and pads are provided for optional pull-up and pull-down
resistors. Two of the GPIO pins are connected to push buttons, and pads are provided
for switch debouncing. Finally, headers are provided for ICSP and I2C, allowing the
user to program and communicate with the MCP19111.
2.2
GETTING STARTED
The MCP19111 Evaluation Board is fully assembled, programmed and tested to
evaluate and demonstrate the MCP19111 operational capabilities.
2.2.1
Power Input and Output Connection
2.2.1.1
POWERING THE MCP19111 EVALUATION BOARD
The MCP19111 Evaluation Board is fully assembled, programmed, tested and ready to
begin evaluation. Apply positive input voltage to the VIN terminal and its return to the
PGND terminal. The maximum input voltage should not exceed 12V. An electronic load
or resistive load can be used for evaluation, or the intended system load can be
connected. Electronic loads attempt to sink current at 0V during startup; a resistive load
or constant resistance is recommended for start-up evaluation. Connect the positive
voltage terminal of the load to the VOUT terminal on the MCP19111 Evaluation Board
and connect the negative or return side of the load to the PGND terminal.
2.2.1.2
BOARD TESTING
To test the board:
1. Apply greater than 5V to the input for proper operation, no minimum load is
required to regulate the output to 1.8V.
2. Press push button BT1. This button enables the internal synchronous drivers of
the MCP19111. This button can be pressed at any time to enable/disable the
internal synchronous drivers of the MCP19111.
3. The measured output voltage should be 1.8V typical. Adjusting the input voltage
and load should not cause the output to vary significantly over the operating
range of the converter.
