LT3972HMSE#TRPBF

Overview

The LT3972HMSE#TRPBF is a high-efficiency, monolithic synchronous step-down switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 3.6V to 33V and delivers up to 3.5A of output current. The device features a fixed switching frequency of 2.45MHz and supports adjustable frequencies from 100kHz to 3MHz. It offers an output voltage range of 790mV to 30V with a typical quiescent current of 75µA and a shutdown supply current of 30µA. Housed in a thermally enhanced 10-lead MSOP package, it functions within an operating temperature range of -40°C to +125°C.

Feature Summary

Integrated synchronous rectification architecture for high efficiency across load ranges
Wide input voltage capability supporting direct bus or battery power sources
Adjustable switching frequency allows optimization for size versus performance
Thermal regulation and cycle-by-cycle current limit protection

Applications

Industrial point-of-load regulation
Battery-powered instrumentation
Distributed power systems
Automotive electronics

Procurement Notes

Verify the specific suffix TRPBF indicates tape-and-reel packaging when ordering. Confirm the HMSE grade meets required thermal and electrical specifications for your application environment. Cross-reference the manufacturer datasheet for exact pinout and recommended external component values to ensure compliance with design requirements.

Selection Notes

Select this component for applications requiring high current density and wide input voltage flexibility. The fixed 2.45MHz frequency minimizes passive component size compared to lower-frequency alternatives. Ensure adequate thermal management due to the power dissipation characteristics inherent in the MSOP package form factor under heavy loads.

Part Context

This part belongs to the LT3972 family of synchronous buck regulators designed for demanding industrial and automotive environments. It shares architectural similarities with other high-voltage buck converters but distinguishes itself through its specific 33V input rating and 3.5A current capacity, targeting compact power solutions.
