LT8603JUJ#PBF

Overview

The LT8603JUJ#PBF is a quad-output power management IC from Analog Devices, housed in a 40-lead QFN (6x6 mm) package. It integrates two high-voltage monolithic buck regulators, one low-input buck regulator, and a boost controller. The device supports an input voltage range of 2.6 V to 42 V. Output currents are rated at 1.5 A, 1.8 A, and 2.5 A for the respective channels. Operating temperatures span from -40°C to +125°C, with quiescent current as low as 100 nA.

Feature Summary

Integrates three independent buck converters and one boost controller within a single compact package
Supports wide input voltage ranges suitable for diverse power source requirements
Features ultra-low shutdown current for enhanced energy efficiency in battery-powered systems

Applications

Industrial equipment requiring multiple regulated voltage rails
Distributed power architectures in server infrastructure
Automotive electronics with varying input voltage conditions

Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm package type and temperature grade. Ensure compatibility with PCB footprint dimensions for the 40-QFN configuration. Cross-reference thermal performance data with system heat dissipation capabilities to maintain operation within the specified -40°C to +125°C range.

Selection Notes

Select this component when a single IC solution is required to generate four distinct output voltages from a wide input range. It is suitable for designs prioritizing board space reduction over discrete solutions. Consider the specific current ratings of each channel to ensure adequate load capacity for all connected subsystems without exceeding thermal limits.

Part Context

This part belongs to the LT8603 series of highly flexible multi-output regulators. It combines high-voltage and low-voltage buck technologies with boost control to address complex power distribution needs. The series is designed for applications demanding high integration and reliability in harsh environments.
