LT3972HMSE#PBF

Overview

The LT3972HMSE#PBF is a high-efficiency, synchronous step-down switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 4.2V to 42V and delivers up to 1.5A of output current. The device integrates the main switch and synchronous rectifier in a compact MSOP-10 package. It features a fixed switching frequency of 2.15MHz and supports adjustable frequencies from 200kHz to 2.5MHz. Quiescent current is minimized at 1.9µA during operation and drops to 2.5µA in shutdown mode. The component functions reliably across an extended temperature range from -40°C to +150°C.

Feature Summary

Integrates high-side and low-side power switches for efficient synchronous rectification
Supports wide input voltage range suitable for industrial and automotive applications
Features programmable switching frequency to optimize external component size
Includes thermal regulation and cycle-by-cycle current limit protection

Applications

Industrial point-of-load regulation
Automotive electronics power distribution
Telecommunications infrastructure power supplies
Battery-powered equipment requiring high efficiency

Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm pinout compatibility and electrical specifications. Ensure the procurement channel provides valid traceability records. Confirm RoHS compliance status directly with the manufacturer or authorized distributors before finalizing orders.

Selection Notes

Select this component when designing systems requiring a wide input voltage range and high efficiency in a small footprint. Consider the thermal performance requirements given the MSOP-10 package constraints. Evaluate the need for external frequency programming versus using the fixed internal oscillator setting.

Part Context

This part belongs to the LT3972 family of synchronous buck regulators designed for high-density power conversion. It shares architectural similarities with other members of the series but differs in package type and specific thermal characteristics. The MSOP-10 variant offers a balance between performance and board space utilization.
