Note the following details of the code protection feature on Microchip devices:
YSTEM
CERTIFIE DBYDNV
== ISO/TS16949==
• 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.
Information contained in this publication regarding device
applications and the like is provided only for your convenience
and may be superseded by updates. It is your responsibility to
ensure that your application meets with your specifications.

1.1 INTRODUCTION
This chapter provides an overview of the MIC23350 Evaluation Board and covers the
following topics:
• MIC23350 Device Short Overview
• What is the MIC23350 Evaluation Board?
• Contents of the MIC23350 Evaluation Board Kit
1.2 MIC23350 DEVICE SHORT OVERVIEW
The MIC23350 device is a compact, high-efficiency, low-voltage, 3A continuous
current, synchronous step-down regulator. The HyperLight Load™ provides very high
efficiency at light loads, while still having an ultra-fast transient response. The
MIC23350 device’s output voltage is set by two V
pins, which allow for nine possible combinations. Table 2-1 details the possible
combinations and the resulting output voltage. The 2.4V to 5.5V input voltage range,
low shutdown and quiescent currents make the MIC23350 device ideal for single-cell
Li-Ion battery-powered applications. The 100% duty cycle capability provides
low-dropout operation, extending the operating range in portable systems.
An open-drain Power Good (PG) output is provided to indicate when the output voltage is
within 9% of regulation and facilitates output voltage monitoring and supply sequencing.
When set in shutdown (EN = GND), the MIC23350 device draws a typical current of 1.5 µA.
