LT3641EFE#TRPBF

Overview

The LT3641EFE#TRPBF is a dual monolithic synchronous buck switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 2.5V to 42V and delivers up to 1.3A per channel. The device features adjustable output voltages, a programmable switching frequency from 350kHz to 2.5MHz, and low quiescent current of 275µA. Packaged in a TSSOP-EP-28 surface-mount format, it supports operation between -40°C and +125°C.

Feature Summary

Integrates two independent synchronous buck converters within a single compact package
Includes integrated power-on reset and watchdog timer functions for system protection
Supports wide input voltage ranges suitable for industrial and automotive applications

Applications

Industrial control systems requiring dual isolated or non-isolated rails
Automotive electronics utilizing high-voltage bus architectures
Embedded systems needing efficient multi-rail power distribution

Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm tape-and-reel packaging configuration. Ensure compatibility with required thermal management solutions given the TSSOP-EP-28 package. Cross-reference pinouts and electrical characteristics with the latest datasheet revision to avoid integration errors during design-in.

Selection Notes

Select this component when dual-channel regulation is required from a single high-voltage source. Consider the integrated reset and watchdog features if system reliability is critical. Evaluate thermal performance requirements based on the expected load currents and ambient operating temperatures within the target enclosure.

Part Context

This part belongs to the LT3641 family of dual synchronous step-down regulators. It shares architectural similarities with other high-voltage buck controllers but distinguishes itself through integrated monitoring features. The family targets applications demanding space-constrained, high-efficiency power conversion solutions.
