LT3971IMSE16#PBF

Overview

The LT3971IMSE16#PBF is a synchronous step-down switching regulator manufactured by Analog Devices. It operates with an input voltage range of 4.3V to 38V and delivers up to 1.2A of output current. The device features a fixed 2MHz switching frequency and supports adjustable output voltages from 1.19V to 30V. It utilizes a 16-lead MSOP package with an exposed pad for thermal management. Quiescent current is specified at 2.8µA during regulation and drops to 1.7µA in operation, ensuring high efficiency across load conditions.

Feature Summary

Integrates a high-efficiency internal power switch and boost Schottky diode within the monolithic buck topology.
Features low ripple Burst Mode operation to maintain high efficiency at light loads while minimizing output voltage ripple.
Includes an internally compensated current mode control architecture designed for fast transient response and loop stability.

Applications

Industrial systems requiring wide input voltage ranges
Distributed power architectures
Battery-powered equipment

Procurement Notes

Verify the specific suffix and package configuration against official datasheets to ensure compatibility with design requirements. Confirm RoHS compliance status through manufacturer documentation. Check for any recent product change notices regarding epoxy or marking updates. Ensure availability aligns with project timelines as distribution may vary.

Selection Notes

Select this component for designs needing a compact solution with wide input voltage tolerance. The fixed 2MHz frequency allows for smaller passive components compared to lower-frequency alternatives. Consider the 16-lead MSOP package for space-constrained PCB layouts requiring robust thermal dissipation via the exposed pad.

Part Context

This part belongs to the LT3971 family of ultra-low quiescent current buck regulators. It shares architectural similarities with variants like the LT3971EMSE-3.3#PBF but differs in pin count and package type. The IMSE16 designation indicates a specific 16-lead MSOP configuration distinct from the 10-lead MSOP versions found in other series members.
