LT3971EMSE#PBF

Overview

The LT3971EMSE#PBF is a monolithic buck switching regulator manufactured by Analog Devices Inc. It accepts an input voltage range from 4.3V to 38V and delivers up to 1.2A of output current. The device features an adjustable switching frequency between 200kHz and 2MHz, enabling optimization for efficiency or component size. It incorporates a low quiescent current design consuming only 2.8µA during regulation with no load. The IC is housed in a compact 10-lead MSOP package with an exposed thermal pad.

Feature Summary

Adjustable switching frequency allows customization for specific efficiency or size requirements
Low quiescent current operation maintains high efficiency at light loads
Integrated boost Schottky diode and internal compensation simplify circuit design

Applications

Battery-powered portable equipment requiring extended runtime
Industrial systems with wide input voltage ranges
Distributed power architectures in communication infrastructure

Procurement Notes

Verify the exact suffix #PBF indicates lead-free compliance and RoHS adherence. Confirm the MSOP-10 package variant matches your PCB footprint requirements. Ensure the supplier provides valid traceability documentation for Analog Devices components. Cross-reference the manufacturer part number against official Analog Devices databases to avoid counterfeit risks.

Selection Notes

Select this regulator when a fixed 1.2A buck converter is needed with flexible frequency control. The 38V maximum input rating suits applications powered by higher voltage rails. Consider the 10-MSOP package for space-constrained designs requiring adequate thermal dissipation through the exposed pad.

Part Context

This component belongs to the LT3971 family of ultra-low quiescent current step-down regulators. The EMSE designation specifies the MSOP-10 package with industrial temperature range capabilities. It serves as a core power management solution for efficient DC-DC conversion in compact electronic systems.

Replacement Considerations

LT3971IMSE#PBF offers identical electrical performance in the same package but may differ in specific manufacturing lot characteristics. Verify pin compatibility and thermal requirements before substitution.
