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

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

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

°C to +125°C.

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
resistors can be attached to any voltage, including V
ing a jumper between PWR and V
the desired voltage. If the pull-up resistors are not used (the I
pull-up resistors), the PWR pin can be left floating.

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

GND.

• J1 can be used to interface with other I

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.
