INTRODUCTION
MCP16301 SHORT OVERVIEW
This chapter provides an overview of the MCP16301 300 mA D
covers the following topics:
• MCP16301 Short Overview
• What is the MCP16301 300 mA D
• What Does the MCP16301 300 mA D
The MCP16301 device is a highly integrated, high-efficiency, fixed frequency,
step-down DC-DC converter in a popular 6-pin SOT-23 package, that operates from
input voltage sources up to 30V. The integrated features include a high-side switch,
fixed frequency peak current mode control, internal compensation, peak current limit
and overtemperature protection. Minimal external components are needed to develop
a high-efficiency power supply, operating from a high-voltage input.
High-converter efficiency is achieved by integrating the current limited, low resistance,
high-speed N-Channel MOSFET and associated drive circuitry. High-switching
frequency minimizes the size of the external filtering components, resulting in a small
solution size.

rent, while regulating the output voltage from 2.0V to 15V. An integrated, high-perfor-
mance peak current mode architecture keeps the output voltage tightly regulated, even
during input voltage steps and output current transient conditions that are common in
power systems. For this evaluation board, the external components are sized such that
they can fit into a smaller space than a D
nents, namely the Schottky diode and the inductor, limit the maximum output current
for this application to less than 300 mA.
