LT8616IUDE#PBF

Overview

The LT8616IUDE#PBF is a dual synchronous monolithic step-down switching regulator from Analog Devices. It features two independent channels capable of delivering up to 2.5A each, with a combined peak current capability of 6.5A. The device operates with an input voltage range of 3.4V to 42V and provides adjustable output voltages starting from 0.79V. It integrates high-speed MOSFETs and requires minimal external components. The IC is housed in a 28-lead WFQFN package with an exposed pad for thermal dissipation.

Feature Summary

Dual-channel architecture providing independent control over two output rails
High efficiency operation enabled by integrated synchronous rectification
Ultra-low quiescent current consumption for improved light-load performance
Integrated protection mechanisms including thermal shutdown and current limiting

Applications

Industrial automation power supplies
Automotive infotainment and control systems
Telecommunications infrastructure equipment
Point-of-load regulation for digital signal processors

Procurement Notes

Verify the specific suffix 'IUDE' confirms the industrial temperature grade and WFQFN package type. Ensure compatibility with the required output current specifications before ordering. Cross-reference the datasheet revision to confirm pinout consistency with existing designs. Confirm RoHS compliance status as indicated by the '#PBF' designation.

Selection Notes

Select this component when dual isolated or non-isolated outputs are required from a single high-voltage rail. Consider the 42V maximum input rating for automotive or industrial bus applications. Evaluate thermal management requirements due to the high current density in the 28-WFQFN package. Compare against single-channel alternatives if only one output is needed to optimize board space.

Part Context

This part belongs to the LT8616 family of dual synchronous buck regulators. It shares core topology with variants like the LT8616EUDE#PBF but differs in temperature rating and packaging. The series is designed for high-density power conversion where efficiency and size are critical constraints.
