LT8609AEDDM-3.3#PBF

Overview

The LT8609AEDDM-3.3#PBF is a synchronous step-down switching regulator manufactured by Analog Devices Inc., featuring a fixed 3.3V output and 3A current capability. It operates within a 3V to 42V input range, utilizing a 10-WFDFN package with exposed pad for surface mount installation. The device supports adjustable switching frequencies from 200kHz to 2.2MHz and includes shutdown functionality. It maintains a low quiescent current of 2.5µA and functions reliably across an extended temperature range of -40°C to +125°C.

Feature Summary

Integrated synchronous rectification for high efficiency in compact designs
Fixed internal feedback voltage setting for simplified application circuitry
Wide input voltage range supporting various power supply architectures
Low non-switching quiescent current for improved battery life

Applications

Industrial point-of-load regulation
Distributed power systems
Battery-powered equipment
Embedded computing platforms

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and specific lot traceability requirements prior to purchase. Ensure storage conditions adhere to moisture sensitivity level guidelines to prevent package damage during soldering processes.

Selection Notes

Choose this variant when a stable 3.3V rail is required without external resistor networks. Evaluate thermal performance based on PCB copper area and ambient conditions. Consider the 10-WFDFN footprint constraints against available board space. Compare peak current capabilities against maximum load transients to ensure adequate headroom.

Part Context

This component belongs to the LT8609 family of high-efficiency synchronous buck regulators. The series offers multiple package options and output configurations to suit diverse design needs. The 'A' suffix indicates specific electrical characteristics and performance grades defined by Analog Devices for this generation of power management integrated circuits.
