LT8616IFE

Overview

The LT8616IFE is a dual synchronous step-down switching regulator manufactured by Analog Devices Inc. It integrates two independent buck converters capable of delivering up to 3A per channel, with a combined maximum output current of 6.5A. The device operates from an input voltage range of 2.7V to 42V and supports adjustable switching frequencies up to 2.05MHz. Key electrical specifications include a low quiescent current of 6.5µA when both channels are enabled and a shutdown supply current of 1.5µA. The component utilizes a thermally enhanced 28-lead QFN package.

Feature Summary

Dual-channel architecture providing independent control for each buck converter
Integrated high-side and low-side N-channel power switches
Programmable frequency synchronization capability
Built-in soft-start functionality to limit inrush current

Applications

Industrial automation systems
Distributed power architectures
Point-of-load regulation
Battery-powered instrumentation

Procurement Notes

Verify the specific suffix against official documentation to confirm pinout compatibility and thermal pad configuration. Confirm that the requested variant matches the required switching frequency options and package type. Ensure sourcing channels provide valid traceability for quality assurance purposes.

Selection Notes

Select this component for designs requiring two isolated or non-isolated regulated outputs from a single high-voltage rail. Evaluate thermal performance requirements based on the expected load current and ambient temperature conditions. Consider the available switching frequency options to optimize external component size versus electromagnetic interference constraints.

Part Context

This part belongs to the LT8616 family of dual synchronous buck regulators designed for high-efficiency power conversion. It serves as a solution for applications needing compact footprints and multiple voltage rails. The series is characterized by its ability to operate efficiently across wide input voltage ranges while maintaining stable output regulation under varying load conditions.
