LT3680EDD#TRPBF

Overview

The LT3680EDD#TRPBF is a monolithic buck switching regulator manufactured by Analog Devices Inc., designed for high-efficiency power conversion. It accepts input voltages up to 36V and delivers an adjustable output voltage ranging from 0.79V to 30V with a maximum continuous output current of 3.5A. The device features an integrated high-efficiency 95mΩ switch and operates at an adjustable switching frequency between 200kHz and 2.4MHz. It incorporates low ripple Burst Mode operation to maintain efficiency at light loads while keeping output ripple below 15mV in typical applications. The component utilizes current mode topology for fast transient response and loop stability, housed in a 10-WFDFN package.

Feature Summary

Integrates a high-efficiency internal switch and boost Schottky diode within a compact monolithic design.
Supports adjustable switching frequencies from 200kHz to 2.4MHz to optimize performance for specific application requirements.
Employs current mode topology to ensure rapid transient response and robust loop stability under varying load conditions.

Applications

Industrial control systems requiring efficient step-down regulation from higher bus voltages
Distributed power architectures in equipment with 36V input rails
Battery-powered devices needing extended runtime through low quiescent current operation

Procurement Notes

Verify the exact part number suffix against official Analog Devices documentation to confirm tape-and-reel packaging specifications. Ensure compatibility with required thermal management solutions given the DFN package type. Cross-reference electrical parameters such as switching frequency range and output current limits with system design requirements before integration.

Selection Notes

Choose this regulator when input voltages reach up to 36V and output currents exceed 3A are needed. The adjustable frequency feature allows optimization for EMI or component size constraints. Consider the Burst Mode operation for applications demanding high efficiency at light loads without excessive output ripple.

Part Context

This component belongs to the LT3680 family of step-down switching regulators from Analog Devices. It shares architectural similarities with other high-voltage buck converters but is distinguished by its specific 3.5A current capability and wide input voltage range. The family focuses on providing reliable power management solutions for industrial and commercial applications.
