MCP16323 SHORT OVERVIEW
The MCP16323 is a highly integrated, high-efficiency, fixed frequency, synchronous,
step-down DC-DC converter in a popular 16-pin QFN package that operates from input
voltage sources up to 18V. Integrated features include a low resistance high-side
switch, low resistance low-side switch, 1.0 Mhz fixed-frequency peak-current mode
control, internal compensation, power good output, peak current limit, V

age and overtemperature protection. Minimal external components are necessary to
develop a complete step-down DC-DC converter power supply. The MCP16323 draws
less than 10 µA while disabled.
High converter efficiency is achieved by integrating the current limited, low resistance,
high-speed N-Channel MOSFETs and associated drive circuitry. Incorporating both the
upper and lower switches reduces the need for external components. High switching
frequency minimizes the size of external filtering components resulting in an overall
small solution size

The MCP16323 can supply 3A of continuous current while regulating the output voltage
from 0.9V to 5V. An integrated high-performance 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.
