LTM4641IY#PBF

Overview

The LTM4641IY#PBF is a 10A step-down DC/DC microModule regulator that integrates advanced input and load protection circuitry. It features an input voltage range of 4V to 38V and supports output voltages from 0.6V to 6V, making it ideal for high-reliability point-of-load regulation. The module is specifically designed to protect expensive processors and FPGAs from overvoltage and overcurrent conditions through a robust latchoff mechanism.

Why Choose This Part

This module eliminates the need for complex discrete protection circuits by integrating a surge stopper and N-channel MOSFET drivers for both input interrupt and output crowbar protection. Its differential remote sense amplifier ensures accurate regulation at the load, while the current-mode architecture allows easy paralleling for higher output currents.

Applications

Getting Started

Engineers can evaluate this part using the DC1543A demonstration circuit, which showcases the advanced overvoltage and input protection features. When designing a PCB, ensure the 144-pin BGA layout follows the datasheet's thermal via guidelines to manage heat dissipation effectively at full 10A loads.
