LT8601EUJ#TRPBF

Overview

The LT8601EUJ#TRPBF is a triple-channel, current-mode, monolithic synchronous buck switching regulator manufactured by Analog Devices Inc. It operates from an input voltage range of 3 V to 42 V and delivers output currents up to 2.5 A per channel. The device features a programmable power-on reset and allows frequency synchronization via a single adjustable oscillator ranging from 250 kHz to 2.2 MHz. Packaged in a QFN-40 surface-mount format, it supports shutdown functionality and maintains a quiescent current of 70 uA during operation.

Feature Summary

• Integrates three independent synchronous step-down regulators within a single monolithic package
• Features a programmable power-on reset function for system sequencing control
• Supports external clock synchronization with an adjustable frequency range from 250 kHz to 2.2 MHz

Applications

• Automotive multi-rail power distribution systems
• Industrial equipment requiring isolated or synchronized DC-DC conversion
• Embedded systems utilizing multiple voltage rails from a single high-voltage source

Procurement Notes

Verify the specific suffix TRPBF indicates tape-and-reel packaging when sourcing. Confirm the manufacturer part number matches exactly to ensure compatibility with the QFN-40 footprint. Check datasheet revisions for any updates to thermal characteristics or electrical limits before finalizing procurement specifications.

Selection Notes

Select this component when designing circuits that require three distinct regulated outputs derived from a common 3 V to 42 V input rail. It is suitable for applications needing synchronized switching frequencies to minimize electromagnetic interference through phase cancellation. Ensure the design accommodates the QFN-40 package thermal requirements for the intended load conditions.

Part Context

This part belongs to the LT8601 series of triple-channel synchronous buck regulators. It shares architectural similarities with other members like the LT8602 but provides three channels instead of four. The EUJ suffix denotes the specific QFN-40 package variant used for surface-mount assembly.

Replacement Considerations

LT8601EUJ#PBF offers identical electrical performance but utilizes tube packaging instead of tape-and-reel.
