Chapter 1. Product Overview

1.1 INTRODUCTION

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”

1.2 MIC7401 DEVICE SHORT OVERVIEW

The MIC7401 is a powerful, highly integrated, configurable, power-management IC

(PMIC) featuring five synchronous buck regulators, one boost regulator, and

high-speed I

C interface with an internal EEPROM and micro-power shutdown. The

device offers two distinct modes of operation: standby mode and normal mode.

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

C communication or the external STBY pin.

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

°C to +125°C.

MIC7401 TYPICAL APPLICATION

1.3 THE MIC7401 EVALUATION BOARD

The MIC7401 Evaluation Board is designed to demonstrate the core functionality of the

MIC7401 configurable PMIC which includes five independent synchronous buck regu-

lators 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, dif-

ferent 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

C programming

compatible with MIC7400/1 Programming Board ADM00760.

Using the MCP2221 I

C Bridge present on the board, the following internal parameters

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

Chapter 2. Installation and Operation

2.1 INTRODUCTION

The MIC7401 Evaluation Board requires only a single power supply between 2.4V and

5.5V with at least 5A of current capability. No external biasing is required to operate the

MIC7401.

Note that the MIC7401 does not have any reverse battery protection. Applying more

than 5.5V on the input or applying a reverse voltage on the input pins may damage the

device.

The MIC7401 Evaluation Board comes preprogrammed with the following voltages:

• Buck regulator 1: 1.8V

• Buck regulator 2: 1.1V

• Buck regulator 3: 1.8V

• Buck regulator 4: 1.05V

• Buck regulator 5: 1.25V

• Boost regulator: 12V

The MIC7401 PMIC on the Evaluation Board has been designed so that the I

C pull-up

resistors can be attached to any voltage, including V

and V

USB

. This is done by plac-

ing a jumper between PWR and V

USB

, PWR and V

or by providing the PWR pin with

the desired voltage. If the pull-up resistors are not used (the I

C bus interface has other

pull-up resistors), the PWR pin can be left floating.

2.2 GETTING STARTED

To power-up the MIC7401 Evaluation Board, complete the following steps:

1. Connect a suitable power supply to the V

and GND terminals. An ammeter may

be placed between the input power supply and the V

terminal of the evaluation

board to monitor the input current. Ensure that the power supply voltage is mon-

itored at the V

terminals (TP1 and TP2). The ammeter and/or power lead

resistance can reduce the voltage supplied to the input. Keep the power supply

disabled; do not apply power until Step 5.

2. Connect the load to any V

OUT

and GND terminals. The load can be either pas-

sive (resistive) or active (electronic load). An ammeter can be placed between

the load and the V

OUT

terminal of the channel under test. Ensure that the output

voltage is monitored at the V

OUT

terminal.

3. Connect a jumper between V

USB

and PWR or between V

and PWR. This pro-

vides power to the I

C pull-up resistors with the high level corresponding to either

USB power (5V) or V

4. Connect the microUSB type B cable from J2 to a PC in order to enable commu-

nication. The MIC7401 Evaluation Board provides easy interfacing to any PC

using the MCP2221 Bridge.

5. Turn on the power supply.

6. To modify the Output Voltage, Current Limit, Startup Sequence, Soft Start time or

any other feature of any converter, use the I

C Monitor Graphical User Interface

(GUI).

7. Because the MCP2221 and the MIC7401 share the I

C Data and Clock lines, the

MIC2221 must always be powered. This will not interfere with I

communication. When the MIC2221 is not used, it will consume less than

150 µA.

Note: The inductance associated with long wires between the power supply and

the board input may cause voltage spikes at load stepping, start-up into

heavy load or hot wire plug condition. If the spikes exceed the 5.5V

maximum input voltage rating, the MIC7401 may fail.This behavior is

prevented by the C15 capacitor (150 µF tantalum) by absorbing voltage

spikes.

2.3 MIC7401 EVALUATION BOARD CONNECTORS

The MIC7401 Evaluation Board features different connectors for selecting different

functionality and test points for voltage measurements and power-good:

• J16 can be used to Enable or Disable the MIC7401. Placing a jumper between EN

and GND will disable the device. The MIC7401 Evaluation Board features a

pull-up resistor for the EN signal so the PMIC will be enabled by default.

• J3 can be used to monitor different signals with respect to local GND: EN, PG,

POR and STBY.

• J4 can be used to monitor the I

C interface (SDA and CLK) with respect to local

GND.

• J1 can be used to interface with other I

C buses providing SDA, SCL, PWR and

GND access.

• J5, J6, J7, J8, J9 and J10 connectors are provided to measure the output voltages

with respect to local GND for accurate voltage and noise measurements.

2.4 REQUIRED SOFTWARE AND HARDWARE TOOLS

In order to install, use and evaluate the product, there are several software and

hardware tools required to be installed and/or configured.

2.4.1 Requirements

The MIC7401 Evaluation Board requires only a single power supply with 5A (minimum)

current capability. The output load can either be an active (electronic) or passive

(resistive) load.

2.4.2 Required Software

•I

C Monitor 3.1.0 or newer versions

•Microsoft

.NET Framework 4.5 or higher

• Adobe

Acrobat Reader

•Microsoft

Windows 7

2.4.3 Required Hardware

• MIC7401 Evaluation Board

• USB-to-micro-USB Cable

2.4.4 Precautions

The MIC7401 Evaluation Board does not have reverse polarity protection. Applying a

soft voltage to the VIN and GND terminals can damage the device. The maximum

operating rating for V

is 5.5V. Exceeding 5.5V on the VIN could damage the device.
