LT3680IMSE#TRPBF

Overview

The LT3680IMSE#TRPBF is a synchronous step-down switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 3.6V to 36V and delivers up to 3.5A output current. The adjustable output voltage spans from 0.79V to 30V across a single channel. Switching frequency is programmable between 230kHz and 2.45MHz. The device utilizes a 10-MSOP package with an exposed pad for thermal management, supporting operation temperatures from -40°C to 125°C.

Feature Summary

Integrates high-side and low-side N-channel power switches for efficient synchronous rectification
Features internal compensation to simplify external component selection
Includes built-in soft-start capability to limit inrush current during startup

Applications

Industrial control systems requiring regulated power rails
Distributed power architectures in embedded equipment
Battery-powered devices needing efficient voltage conversion

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing components. Confirm that the IMSE designation corresponds to the industrial temperature grade (-40°C to 125°C) required for your application environment. Ensure compatibility with the 10-MSOP footprint on your PCB layout to guarantee proper mechanical fit and thermal dissipation through the exposed pad.

Selection Notes

Select this component when a wide input voltage range up to 36V is necessary alongside moderate current delivery. Consider the programmable switching frequency to optimize the trade-off between efficiency and passive component size. Evaluate the thermal performance requirements given the exposed pad design, which aids in heat transfer to the board copper planes for sustained operation under load conditions.

Part Context

This part belongs to the LT3680 family of monolithic switching regulators designed for compact power solutions. It integrates the controller, drivers, and power switches into a single small outline package. The series targets applications where space constraints and high efficiency are critical, offering a robust alternative to discrete switcher designs while maintaining ease of implementation.
