LT8609AIMSE16#TRPBF

Overview

The LT8609AIMSE16#TRPBF is a high-speed synchronous step-down switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 3 V to 42 V and delivers a continuous output current of 2 A, with a peak capability of 3 A. The device features adjustable output voltage starting from 0.782 V and supports switch frequencies between 200 kHz and 2.2 MHz. It consumes only 1.7 uA of non-switching quiescent current in standby mode. The component is housed in a 16-lead MSOP package with an exposed pad and is rated for operation temperatures from -40°C to +150°C.

Feature Summary

• High efficiency synchronous buck topology designed for compact power solutions
• Ultra-low non-switching quiescent current consumption for extended battery life
• Wide input voltage range supporting various industrial and automotive supply rails
• Integrated frequency synchronization and spread spectrum modulation capabilities

Applications

• Industrial automation controllers and PLCs
• Automotive infotainment and sensor systems
• Portable test and measurement equipment
• Distributed power architectures in telecom infrastructure

Procurement Notes

Verify the specific suffix and tape-and-reel packaging details against the manufacturer's latest datasheet before ordering. Confirm that the MSOP-16 package variant matches your PCB footprint requirements. Ensure compliance with RoHS directives and check for any recent production changes or lifecycle status updates directly from Analog Devices.

Selection Notes

Select this component when a wide input voltage range up to 42 V is required alongside high efficiency at moderate currents. The 2 A continuous rating suits applications needing reliable power delivery without excessive thermal management. Consider the 1.7 uA quiescent current for battery-operated designs requiring long standby times. Evaluate the 2.2 MHz maximum switching frequency to minimize external passive component sizes.

Part Context

This part belongs to the LT8609 family of high-speed synchronous buck regulators. The AIMSE16 designation indicates the Automotive grade temperature range and the MSOP-16 package type. It shares core architecture with other LT8609 variants but offers specific performance characteristics tailored for robust industrial and automotive environments.

Replacement Considerations

LT8609AHMSE16#TRPBF: Similar performance with potentially different thermal or electrical specifications; verify pinout compatibility. LT8609AJMSE16#TRPBF: Check if shutdown functionality aligns with system requirements as some variants may differ in control features.
