LT3976HMSE#TRPBF

Overview

The LT3976HMSE#TRPBF is a monolithic buck switching regulator from Analog Devices. It accepts an input voltage range up to 40V and delivers a maximum output current of 5A. The device features an adjustable switching frequency ranging from 200kHz to 2.25MHz. It incorporates an ultralow quiescent current design, drawing only 3.3μA at 12VIN when regulating to 3.3VOUT. The component operates within a temperature range of -40°C to 150°C.

Feature Summary

Ultralow quiescent current consumption for extended battery life
Wide input voltage tolerance supporting high-voltage applications
Adjustable switching frequency allows optimization for efficiency or size
Integrated synchronous rectification for high conversion efficiency

Applications

Battery-powered portable equipment requiring low standby power
Industrial systems with wide input voltage variations
Automotive electronics operating in harsh thermal environments
Point-of-load regulation in communication infrastructure

Procurement Notes

Verify the specific suffix TRPBF indicates tape-and-reel packaging. Confirm the HMSE variant meets the required thermal performance specifications. Ensure compatibility with the target PCB footprint for the 16-TFSOP package. Validate that the supplier provides original manufacturer documentation to guarantee authenticity.

Selection Notes

Select this component when input voltages exceed standard 36V limits but remain below 40V. Choose based on the requirement for minimal no-load current drain in always-on systems. Consider the exposed pad thermal design for heat dissipation at full load. Evaluate the need for external frequency synchronization if noise immunity is critical.

Part Context

This part belongs to the LT3976 family of high-efficiency step-down converters. It shares architectural similarities with other Analog Devices buck regulators but distinguishes itself through its specific 40V rating and 5A capability. The MSOP-16/TF-SOP package offers a compact solution for space-constrained designs compared to larger industrial packages.
