MCP16311 Building Block Solutions

Overview

TopologyBuck Converter
Input voltage4.5-30 V
Output 13.3 V / 1 A
IC revision2

Description

The MCP16311/2 is a compact, high-efficiency, fixed frequency, synchronous step-down DC-DC converter in an 8-pin MSOP, or 2 x 3 mm TDFN package that operates from input voltage sources up to 30V. Integrated features include a high-side and a low-side switch, fixed frequency peak current mode control, internal compensation, peak current limit and overtemperature protection. The MCP16311/2 provides all the active functions for local DC-DC conversion, with fast transient response and accurate regulation.

Features

  • Modular Design for Easy Evaluation of Each Converter
  • Clearly Labeled Sub-Modules for Quick Identification
  • Pre-Configured Output Voltages for Typical Use Cases Building Block Solutions – Switchers User’s Guide User Guide © 2025 Microchip Technology Inc. and its subsidiaries DS50003984A - 2
  • Test Points and Connectors for Easy Measurement and Integration

Typical applications

  • Distributed Power Supplies, PIC®/dsPIC® Microcontroller Bias Supply, 24V Industrial Input DC-DC
  • Laptop Computers
  • Automotive Battery Regulation
