Overview

Topology	Buck Converter
Input voltage	4.4-50 V
Output 1	24 V

Description

The MCP16331 device is a highly integrated, high-efficiency, fixed-frequency, step-down DC-DC converter in a popular 6-pin SOT-23 or 8-pin 2 mm x 3 mm TDFN package, that operates from input voltage sources up to 50V. Integrated features include a high-side switch, fixed frequency Peak Current-Mode control, internal compensation, peak current limit and overtemperature protection. Only a few external components are necessary to develop a complete step-down DC-DC converter power supply.
