LT8609AEDDM#PBF

Overview

The LT8609AEDDM#PBF is a synchronous step-down DC/DC converter from Analog Devices, housed in a 10-WFDFN package. It features an input voltage range of 3V to 42V and delivers up to 3A output current. The device supports adjustable switching frequencies between 200kHz and 2.2MHz. It includes a fixed 0.782V reference for output regulation and offers low quiescent current operation. The component operates within a junction temperature range of -40°C to +125°C and integrates protection features such as thermal shutdown.

Feature Summary

Synchronous buck topology with integrated power switches
Adjustable switching frequency for optimization of size and efficiency
Low quiescent current operation extending battery life
Thermal shutdown protection for enhanced reliability

Applications

Industrial control systems
Distributed power architectures
Battery-powered equipment
Point-of-load regulation

Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and tube packaging when ordering. Confirm availability status as supply conditions may vary by region. Ensure the selected variant matches the required output configuration, as this part number denotes the adjustable version. Cross-reference the datasheet for latest assembly site information and environmental declarations prior to procurement.

Selection Notes

Select this component for applications requiring high input voltages up to 42V in a compact footprint. The adjustable frequency feature allows designers to trade off between electromagnetic interference and external component size. Consider the 10-WFDFN package for surface-mount assembly constraints. Evaluate thermal performance at maximum load currents to ensure operation within the specified temperature limits without additional heatsinking.

Part Context

This part belongs to the LT8609 family of Silent Switcher regulators designed for high efficiency and low EMI. The LT8609AEDDM#PBF specifically represents the adjustable output variant in a DFN package. It complements fixed-output versions like the LT8609AEDDM-3.3#PBF and LT8609AEDDM-5#PBF within the same product line, offering flexibility for custom voltage rails.
