LT8609BEMSE#TRPBF

Overview

The LT8609BEMSE#TRPBF is a synchronous step-down switching regulator from Analog Devices, housed in a 10-MSOP package with an exposed pad. It supports an input voltage range of 3V to 42V and delivers up to 3A of continuous output current. The device features adjustable output voltages starting from 0.782V. Key electrical parameters include a quiescent current of 1.5µA and a programmable switching frequency ranging from 200kHz to 2.2MHz. It operates within a junction temperature range of -40°C to 125°C.

Feature Summary

Integrated high-side N-channel MOSFETs enable efficient synchronous rectification for improved performance.
Programmable switching frequency allows optimization for specific design requirements regarding size and efficiency.
Low quiescent current consumption extends battery life in portable applications during standby modes.

Applications

Industrial equipment power distribution
Point-of-load regulation systems
Battery-powered instrumentation

Procurement Notes

Verify the exact suffix against official Analog Devices documentation to confirm pinout and thermal characteristics. Ensure compatibility with your PCB footprint, as the MSOP-10EP package requires specific soldering techniques for the exposed pad. Confirm RoHS compliance status through the manufacturer's latest material declaration before finalizing procurement.

Selection Notes

Select this component when a wide input voltage range up to 42V is required alongside moderate current capabilities. The adjustable output feature provides flexibility for various logic levels. Consider the thermal performance of the MSOP-10EP package relative to your expected load conditions and ambient temperatures to ensure reliable operation without excessive heatsinking.

Part Context

This part belongs to the LT8609 family of high-efficiency synchronous buck regulators. It shares architectural similarities with other members like the LT8609A but may differ in specific electrical tolerances or thermal ratings. The family is designed to replace linear regulators in applications requiring higher efficiency and lower heat dissipation under similar operating conditions.
