LT8609AEDDM#TRPBF

Overview

The LT8609AEDDM#TRPBF is a synchronous step-down switching regulator from Analog Devices, housed in a 10-WFDFN package with an exposed pad. It supports an input voltage range of 3V to 42V and delivers up to 3A of output current. The device features adjustable output voltages starting from 0.782V and operates at switch frequencies between 200kHz and 2.2MHz. Designed for high efficiency, it includes integrated soft start and thermal regulation. The component functions within a junction temperature range of -40°C to 125°C.

Feature Summary

Integrated synchronous rectification for high conversion efficiency
Wide input voltage capability supporting industrial power rails
Adjustable switching frequency to optimize performance or size
Built-in protection mechanisms including thermal shutdown

Applications

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

Procurement Notes

Verify the specific suffix #TRPBF confirms tape and reel packaging when ordering. Confirm the 'A' grade designation matches required electrical tolerances. Ensure the 10-DFN footprint aligns with the target PCB layout. Check for RoHS compliance status if environmental regulations apply. Validate availability through authorized distributors as supply may vary.

Selection Notes

Select this part for applications requiring a compact solution with high input voltage tolerance. The 3A continuous current rating suits moderate load requirements. Consider the 10-DFN package for space-constrained designs. Evaluate the 200kHz to 2.2MHz frequency range against EMI constraints. Compare against other LT8609 variants if different pinouts or current ratings are needed.

Part Context

This component belongs to the LT8609 family of synchronous buck regulators. It shares core architecture with other members like the LT8609EMSE but differs in package type. The family is designed for high-efficiency DC/DC conversion. It complements lower-current variants like the LT8606 and higher-current options like the LT8640.
