LT8609AIMSE#TRA1PBF

Overview

The LT8609AIMSE#TRA1PBF is a synchronous step-down switching regulator from Analog Devices, housed in a 10-MSOP package with an exposed thermal pad. It supports an input voltage range of 3V to 42V and delivers up to 2A of continuous output current. The device features a fixed 2MHz switching frequency and adjustable output voltages starting from 0.782V. It operates within a junction temperature range of -40°C to 150°C and maintains a low non-switching quiescent current of 1.7µA.

Feature Summary

Integrated high-speed synchronous buck topology for efficient power conversion
Fixed 2MHz switching frequency enabling compact external component sizing
Low non-switching quiescent current for enhanced battery life in standby modes

Applications

Industrial distributed power systems
Portable instrumentation requiring high efficiency
Automotive electronics operating at elevated temperatures

Procurement Notes

Verify the specific suffix TRA1PBF against official documentation to confirm tape and reel packaging specifications. Confirm that the 'I' grade designation aligns with the required industrial temperature range and performance parameters for your design. Cross-reference the manufacturer's latest datasheet to ensure compatibility with your PCB layout and thermal management strategy.

Selection Notes

Select this component when a fixed 2MHz frequency is preferred over adjustable options to minimize board space. Ensure the application requires an MSOP-10 footprint with an exposed pad for adequate thermal dissipation. Verify that the 2A output current capability meets the load requirements without exceeding the thermal limits of the chosen package under expected ambient conditions.

Part Context

This part belongs to the LT8609 family of synchronous buck regulators designed for high-efficiency applications. The AIMSE variant specifically denotes the industrial temperature grade and the MSOP-10 package configuration. It shares core architecture with other LT8609 models but differs in package type and specified operating temperature ranges.
