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
allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.

1.2 WHAT THE MCP1650 BOOST CONTROLLER EVALUATION BOARD IS

The MCP1650 Boost Controller Evaluation Board is used to evaluate and demonstrate
Microchip Technology’s MCP1650/51/52/53 Boost Controller product family. This
board uses the MCP1650/51/52/53 in two high-power, boost-converter applications.
The first application features the MCP1651 (8-pin MSOP) with the low battery detect
feature. The input voltage for the MCP1651 application is 2.8V to 4.8V, with the output
boosted to 5V. The second application uses the MCP1653 (10-pin MSOP), which
features both the low battery detect and power good features. The input voltage for this
application is 3.3V, with the output boosted to 12V.

Chapter 2. Installation and Operation

2.1 INTRODUCTION

The MCP1650 Boost Controller Evaluation Board is designed to demonstrate
Microchip’s family of high-frequency boost controllers. The product family consists of
four high-frequency, boost-converter devices having different combinations of features.
All devices in the family feature 750 kHz high-frequency, low quiescent current,
shutdown capability and the MSOP package. The MCP1650 8-pin MSOP is the base
device. The MCP1651 8-pin MSOP includes all of the features of the MCP1650, with
the addition of a low battery detect and low battery output (LBO
MCP1652 8-pin MSOP includes all of the features of the MCP1650, with the addition
of a power good (PG) indicator. The PG indicator is an open-drain output that is
high-impedance when the output voltage of the converter is within ±15% of its intended
regulation range. When the output of the regulator is not within the ±15% range, the PG
pin will sink up to 10 mA. The MCP1653 10-pin MSOP has all features; the LBO
PG, along with the base features of the MCP1650.

2.2 FEATURES

The MCP1650 Boost Controller Evaluation Board has the following features:

• Evaluation of the MCP1651 in a boost application configured in the Bootstrap
mode. This application circuit will regulate the output to 5V while delivering 1A of
current as the input voltage varies from 2.8V to 4.8V.

• Evaluation of the MCP1653 in a boost application configured in the non-Bootstrap
mode. This application circuit will regulate the output voltage to 12V while
delivering 400 mA of output current as the input voltage varies from 3.0V to 3.6V.

2.3 GETTING STARTED

The MCP1650 Boost Controller Evaluation Board is fully assembled and tested for
evaluation and demonstration of the MCP1650 family of boost controllers. This board
requires the use of external lab supplies and loads. Both application circuits have a
fuse for input overcurrent protection. As with all boost converters, there is a path from
V

to V

IN

put, there is no means of protecting the inductor and diode, so an external fuse is
provided.

MCP1651R Application Circuit

1. Powering the MCP1651 bootstrap application circuit:

- Apply the input voltage to the surface-mount test points provided. The input

- Connect the positive side of the input source (+) to the +V

 2004 Microchip Technology Inc. DS51462A-page 5

through the boost inductor and output diode. In the case of a shorted out-

OUT

voltage source should be limited to the 2.8V to 4.8V range to regulate the
5V output. The input voltage must not exceed the +5.5V maximum rating of
the MCP165X. The source current necessary to regulate the output voltage
to +5V at 1A should be approximately 3A.

GND test point (TP4) located next to +V

MCP1650/1/2/3 Evaluation Board User’s Guide

- The Under Voltage Lockout (UVLO) feature will prevent the MCP1651 from
starting the converter until the input voltage is above the minimum thresh­old. Once the input voltage is raised above the UVLO threshold, the
converter will begin to boost the output voltage up to 5V. The output voltage
is fed back to the input so that, once the Boost converter has started, it can
run down to lower input voltages at reduced load currents.

2. Applying the load to the MCP1651 bootstrap application circuit:

- To apply a load to the MCP1651 application circuit, the positive side of the
load (+) should be connected to the +V
side of the load should be connected to the GND test point (TP3). The
maximum load current should not exceed 1A while the input voltage is
within the range specified for this application (2.8V to 4.8V).

3. Using the shutdown feature of the MCP1651 application circuit:

- To shutdown the MCP1651, use a jumper wire to connect the SHDN
point (TP5) to the GND test point (TP4). By grounding the shutdown pin, the
MCP1651 will enter the shutdown state and minimum quiescent current will
be drawn from the input source. To resume normal operation, remove the
jumper pin from the SHDN

test point to ground and the MCP1651 will start.

4. Low Input Status LED:

- The MCP1651 has a low input voltage status indicator that will provide
visual indication (via a LED) when the input voltage is below 3V. This LED
will illuminate to provide a warning that the input voltage is approaching the
minimum 2.8V input voltage.

MCP1653S Application Circuit

1. Powering the MCP1653 non-bootstrap application circuit:

- Apply the input voltage to the surface-mount test points provided. The input
voltage source should be limited to the 3.0V to 3.6V range to regulate the
12V output. The input voltage must not exceed the +5.5V maximum rating
of the MCP165X. The source current necessary to regulate the output
voltage to +12V at 0.4A should be a minimum of approximately 3A.

- Connect the positive side of the input source (+) to the +V
(TP6). Connect the negative, or return side, (–) of the input source to the
GND test point (TP8) located next to +V

IN

- The UVLO feature will prevent the MCP1653 from starting the converter
until the input voltage is above the minimum threshold. Once the input
voltage is raised above the UVLO threshold, the converter will begin to
boost the output voltage up to 12V. To maintain regulation of the 12V output,
the input voltage range should be between 3.0V and 3.6V.

2. Applying the load to the MCP1653 non-bootstrap application circuit:

- To apply a load to the MCP1653 application circuit, the positive side of the
load (+) should be connected to the +V

2 test point (TP7). The negative

OUT

side of the load should be connected to the GND test point (TP10). The
maximum load current should not exceed 0.4A while the input voltage is
within the range specified for this application (3.0V to 3.6V).

3. Using the shutdown feature of the MC1653 application circuit:

- To shutdown the MCP1653, use a jumper wire to connect the SHDN
point (TP9) to the GND test point (TP8). By grounding the shutdown pin, the
MCP1653 will enter the shutdown state and minimum quiescent current will
be drawn from the input source. To resume normal operation, remove the
jumper pin from the SHDN

test point to ground and the MCP1653 will start.

4. Low Input Status LED:

- The MCP1653 has a low input voltage status indicator that will provide
visual indication (via a LED) when the input voltage is below 3V. This LED
will illuminate to provide a warning when the input voltage is at the minimum

3.0V input voltage.

5. Power Good Status Indicator.

- The MCP1653 has a power good status indicator that will provide a visual
indication (via a LED) when the output voltage of the application circuit is
more than ±15% out of regulation. D4 will illuminate to indicate that the
output voltage is out of regulation.
