LT8609AEDDM-3.3#TRPBF

Overview

The LT8609AEDDM-3.3#TRPBF is a synchronous step-down switching regulator manufactured by Analog Devices Inc., featuring a fixed 3.3V output and a 3A current rating. It operates with an input voltage range of 3V to 42V and supports adjustable switching frequencies from 200kHz to 2.2MHz. The device utilizes a 10-WFDFN package with exposed pad for surface mount installation. It includes integrated soft-start, tracking capabilities, and thermal regulation within an operating temperature range of -40°C to 125°C.

Feature Summary

Synchronous buck topology providing high efficiency across wide load ranges
Integrated soft-start minimizes inrush current during power-up sequences
Thermal regulation reduces switching frequency under high thermal stress conditions

Applications

Industrial point-of-load regulation
Distributed power systems
Automotive electronics

Procurement Notes

Verify the specific suffix #TRPBF confirms tape-and-reel packaging when ordering. Confirm the A-grade designation matches required performance specifications. Ensure the DFN-10 footprint aligns with PCB layout constraints. Validate RoHS compliance status against current regulatory requirements before finalizing procurement.

Selection Notes

Select this component for applications requiring a fixed 3.3V rail from higher voltage sources up to 42V. The 3A output capability suits moderate power loads. Consider the 200kHz to 2.2MHz frequency range for balancing efficiency and passive component size. Verify that the 10-lead DFN package fits the available board space and thermal dissipation needs.

Part Context

This part belongs to the LT8609 family of high-efficiency synchronous buck regulators. It shares architectural similarities with other members like the LT8609AJDDM variants but differs in grade and specific electrical tolerances. The family targets compact designs requiring low external component counts and robust thermal performance in small footprints.
