LT3680HMSE#TRPBF

Overview

The LT3680HMSE#TRPBF is a synchronous step-down switching regulator manufactured by Analog Devices Inc. It features an integrated 36V, 3.5A power switch and operates at a fixed 2.4MHz switching frequency. The device delivers a quiescent current of 75µA in shutdown mode. It supports output voltages from 0.79V to 30V with an input voltage range of 3.6V to 36V. The component is housed in a 10-lead MSOP package with an exposed thermal pad.

Feature Summary

Integrates a high-efficiency synchronous rectifier and a 3.5A power switch within a single compact package.
Utilizes constant-frequency peak current mode control architecture for rapid transient response.
Includes programmable soft-start capability to limit inrush current during startup sequences.

Applications

Industrial point-of-load regulation
Battery-powered equipment power management
Distributed power systems

Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm tape-and-reel packaging configuration. Ensure that the selected variant matches the required operating temperature range and electrical specifications for the target application environment before finalizing procurement orders.

Selection Notes

Select this component when designing systems requiring high efficiency and low noise at elevated switching frequencies. Consider the thermal performance of the exposed pad layout and ensure adequate PCB copper area for heat dissipation. Verify compatibility with external compensation components to maintain stability across the full load and line conditions.

Part Context

This part belongs to the LT3680 family of synchronous buck regulators designed for applications demanding high power density. It shares architectural similarities with other members of the series but differs in package type and specific thermal characteristics. The device complements Analog Devices' portfolio of high-performance power management solutions.
