LT3641EFE#PBF

Overview

The LT3641EFE#PBF is a dual monolithic buck switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 4 V to 42 V and delivers up to 1.3 A per channel. The device features adjustable output voltages, a switch frequency ranging from 350 kHz to 2.5 MHz, and a typical quiescent current of 275 uA. Packaged in a TSSOP-EP-28 format, it supports operation between -40°C and +125°C.

Feature Summary

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

Applications

Industrial control systems requiring dual isolated rails
Automotive electronics utilizing high-voltage bus architectures
Telecommunications infrastructure power distribution units

Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm pinout compatibility and thermal performance characteristics. Ensure the procurement source provides valid traceability records. Confirm that the component meets all relevant environmental compliance standards required for your specific deployment region before finalizing acquisition.

Selection Notes

Select this component when dual regulated outputs are necessary from a single high-voltage source. The integrated reset and watchdog functions reduce external component count compared to discrete solutions. Evaluate thermal requirements based on the TSSOP-EP-28 package capabilities under maximum load conditions.

Part Context

This part belongs to the LT3641 series of dual buck regulators. It shares functional similarities with the LT3640 but offers extended input voltage support. The EFE suffix denotes the TSSOP-EP-28 package variant, distinguishing it from QFN options like the IUFD suffix.
