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 MIC45404 Evaluation Board and covers the
following topics:
• MIC45404 Device Short Overview
• MIC45404 Evaluation Board Overview
• What the MIC45404 Evaluation Board User’s Guide Kit Contains
1.2
MIC45404 DEVICE SHORT OVERVIEW
The MIC45404 device is a 19V, 5A ultra-low profile, synchronous step-down regulator
module optimized for high efficiency at low output voltages. The module incorporates
a DC-to-DC regulator, bootstrap capacitor, high-frequency input capacitor and an
inductor in a single package. The module pinout is optimized to simplify the Printed
Circuit Board (PCB) layout process. This highly integrated solution expedites system
design and improves product time to market. The internal MOSFETs and inductor are
optimized to achieve high efficiency at low output voltage. Due to the fully optimized
design, MIC45404 can deliver up to 5A current with a wide input voltage range
of 4.5V to 19V.
The MIC45404 is available in a 54-lead 6 mm × 10 mm × 2.0 mm QFN package with a
junction operating temperature range from -40°C to +125°C.
1.3
MIC45404 EVALUATION BOARD OVERVIEW
The MIC45404 Evaluation Board is intended to facilitate the evaluation of the
MIC45404 power module under various settings and operating conditions.
The basic parameters of the MIC45404 Evaluation Board are a VIN supply of 4.5V to
19V, an output voltage of 0.7V to up to 3.3V at 5A.
Due to the optimized pinout of the MIC45404, the evaluation board can achieve a 2-layer
only routing (top and bottom), while internal planes are connected to GND and kept as
solid as possible for better thermal performance (see Appendix A. “Schematic and
Layouts”).
Also, an on-board load transient generator circuit and connections for loop gain
measurements are provided.

USER’S GUIDE
Chapter 2. Installation and Operation
2.1
INTRODUCTION
The MIC45404 Evaluation Board requires only a single power supply with at least 5A
current capability. The MIC45404 has an internal VDDA LDO, so no external linear
regulator is required to power the internal biasing of the module.
WARNING
The evaluation board does not have reverse polarity protection. Applying a negative
voltage to the VIN terminal may damage the device. The maximum VIN operating voltage
of the MIC45404 Evaluation Board is 19V.
2.2
GETTING STARTED
To power up the MIC45404 Evaluation Board, the following steps must be completed:
1. Connect a power supply to the VIN and GND_IN terminals. An ammeter may be
placed between the input supply and the VIN terminal to the evaluation board.
Ensure that the supply voltage is monitored at the VIN terminal (CON1 or J2). 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 the VOUT and GND_OUT terminals.The load can be either
passive (resistive) or active (electronic load). An ammeter can be placed
between the load and the VOUT terminal. Ensure that the output voltage is
monitored at the VOUT terminal (CON5 or J1). Alternatively, for high-speed load
transient testing at low output voltages, the on-board load transient generator
can be used (see Section 2.3 “MIC45404 Evaluation Board Operation”).
3. An EN/DLY connector (J5) is provided on the evaluation board. In the MIC45404,
the EN/DLY pin is internally pulled up by a 2 µA current source. Keep the
MIC45404 disabled by installing a jumper across J5-2/J5-3 or by driving J5-2 low
externally. Do not enable until Step 6.
4. ILIM, FREQ, VOSET0, VOSET1 selection inputs.
The MIC45404 can be programmed through the pins’ setting for current limit (at
J7), switching frequency (at J8) and output voltage (at J11, J12).
See Section 2.3 “MIC45404 Evaluation Board Operation” for the desired
selection.
5. Turn on the VIN power supply.
6. Enable the MIC45404 by removing the jumper across J5-2/J5-3, or by driving
EN/DLY (J5-2) high, and verify that the output voltage is regulated to the desired
VOUT setting.

Setting the Switching Frequency
The MIC45404 switching frequency can be programmed using the FREQ pin (J8-2), as
shown in Table 2-2 below.

2.3.5
On-Board Load Transient Generator
The MIC45404 Evaluation Board provides circuitry to enable load transient testing with
fast current rise time and fast, yet controlled, fall time. This is done by a fast turn-on,
controlled turn-off MOSFET switch (Q2). Resistive loads (R10 to R13) can be
selectively connected by means of header J15. The total transient load current can be
monitored with a current probe simply by installing a short wire loop at WR1-WR2.
MOSFET Q2 must be driven by an external signal generator, connected at J14, using
a square wave (suggested low level = 0V, high level = 5V-6V). Drive levels can be
adjusted to modify the switching speed of Q2, but should always ensure complete
turn-on and turn-off of Q2 after settling, while not exceeding, its VGS ratings. It is very
important not to exceed the power dissipation limit of R10 to R13. Using 2512 resistors
(1W rating), the constraint is (RLOAD takes the values of R10 to R13):
EQUATION 2-1:
2
V OUT
D ---------------- 1W
R LOAD
Where:
D = The on time duty cycle of Q2
VOUT = The selected output voltage (see Table 2-3)
RLOAD = the value of resistors R10 to R13 (default board
value is 1)
The on-board load transient generator is especially useful when testing at very low
output voltages, since not many active loads can perform well under those conditions,
while current rise times achievable with external load boards are limited by stray
inductance.
2.3.6
Loop Gain Measurement
The MIC45404 Evaluation Board provides injection points and a termination resistor for
AC loop gain measurements. Replace R1 with a suitable value (typically, 20 to 50),
inject the oscillator at J18 through the insulation transformer and connect the A (CH1)
and B (CH2) channels at J17 and J19, respectively, or as indicated by the operating
instructions of the particular loop gain analyzer in use.
