LT8609AHDDM-5#TRPBF

Overview

The LT8609AHDDM-5#TRPBF is a synchronous step-down switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 3V to 42V and provides a fixed 5V output at up to 2A continuous current, with peak capability reaching 3A. The device features a low quiescent current of 1.7µA and supports adjustable switching frequencies from 200kHz to 2.2MHz. It is housed in a compact MSOP-16 package and functions within a junction temperature range of -40°C to +150°C.

Feature Summary

Integrates high-speed synchronous buck topology for efficient power conversion
Features ultra-low non-switching quiescent current for extended battery life
Supports wide input voltage ranges suitable for industrial applications
Includes internal compensation and soft-start functionality

Applications

Industrial distributed power systems
Battery-powered equipment requiring high efficiency
Point-of-load regulation in telecom infrastructure
Automotive electronics operating under wide voltage variations

Procurement Notes

Verify the specific suffix AHDDM against official Analog Devices documentation to confirm the exact pinout, thermal characteristics, and electrical tolerances. Ensure compatibility with your PCB footprint and thermal management strategy. Confirm RoHS compliance status through the manufacturer's latest datasheet before finalizing procurement specifications.

Selection Notes

Select this component when a fixed 5V output is required from a wide input range up to 42V. The MSOP-16 package offers a balance between thermal performance and board space constraints compared to smaller packages. Consider the 1.7µA quiescent current for standby applications and verify that the 2A continuous current rating meets the load requirements without exceeding thermal limits.

Part Context

This part belongs to the LT8609 family of high-speed synchronous buck regulators designed for demanding industrial and automotive environments. The series emphasizes compact size and high efficiency, utilizing advanced control techniques to minimize external component count while maintaining stable regulation across varying load and line conditions.
