Product Introduction

Overview

The LTM4643IY#PBF is a quad DC/DC step-down µModule (power module) regulator produced by Analog Devices Inc. This module is designed to provide high-efficiency power management, particularly suited for mobile and IoT devices. Each output channel can deliver up to 3A of continuous current, and the outputs can be paralleled to achieve a combined output current of up to 12A. The LTM4643 operates over an input voltage range of 4V to 20V and supports an output voltage range of 0.6V to 3.3V, which can be set using a single external resistor.
