•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.”

Chapter 1. Product Overview
1.1INTRODUCTION
This chapter provides an overview of the MIC7401 Evaluation Board and covers the
following topics:
• 1.2 “MIC7401 Device Short Overview”
• 1.3 “The MIC7401 Evaluation Board”
• 1.4 “What the MIC7401 Evaluation Board Kit Includes”
1.2MIC7401 DEVICE SHORT OVERVIEW
The MIC7401 is a powerful, highly integrated, configurable, power-management IC
(PMIC) featuring five synchronous buck regulators, one boost regulator, and
2
high-speed I
device offers two distinct modes of operation: standby mode and normal mode.
C interface with an internal EEPROM and micro-power shutdown. The
MIC7401
EVALUATION BOARD
USER’S GUIDE
In Normal mode, the programmable switching converters can be configured to support
a variety of features, including start-up sequencing, timing, soft-start ramp, output
voltage levels, current-limit levels and output discharge for each channel.
In Standby mode, the PMIC can be configured in a low-power state by either disabling
an output or by changing the output voltage to a lower level. Independent exit from
Standby mode can be achieved either by I
Powering up the MIC7401 directly into Standby mode does not offer the advantages of
Normal mode power-up (sequencing, timing and soft-start ramp control) and should be
avoided.
All switchers provide light-load efficiency with HyperLight Load mode for buck and PFM
mode for boost. An additional benefit of this architecture is a very-low output ripple
voltage throughout the entire load range while still using small inductors and output
capacitors.
The MIC7401 is available in a thermally-efficient, space-saving 36-pin
4.5 mm x 4.5 mm x 0.85 mm FQFN package with an operating junction temperature
range of –40
The MIC7401 Evaluation Board is designed to demonstrate the core functionality of the
MIC7401 configurable PMIC which includes five independent synchronous buck regulators that can deliver a current of 3A and one non-synchronous boost converter with
up to 200 mA of output current from an input voltage of 2.4V to 5.5V. The board features
test points for monitoring each channel’s output voltage, input voltage test points, different functionality connectors and high power turret connectors for both input and
output voltages.
The MIC7401 Evaluation Board also features a 4-pin connector for I
compatible with MIC7400/1 Programming Board ADM00760.
Using the MCP2221 I
can be configured:
• Normal and standby output voltage
• Normal and standby output current limit
• Converters start-up sequencing and delay
• Output ramp rate
• Soft-start ramp
• Global and converter-specific enable
