LT3741IFE-1#PBF

Overview

The LT3741IFE-1#PBF is a fixed frequency synchronous step-down DC/DC controller from Analog Devices. It regulates output current up to 20A with an input voltage range of 6V to 36V and adjustable output voltage from 4V to 34V. The device operates at a switching frequency between 200kHz and 1MHz, drawing a typical quiescent current of 1.8mA. It features integrated soft start, clock synchronization, and enable functions. Packaged in a 20-lead TSSOP with an exposed pad, it supports operation across a temperature range of -40°C to +125°C.

Feature Summary

Synchronous buck topology for high-efficiency power conversion
Integrated constant current and constant voltage regulation modes
Supports external clock synchronization for noise management
Includes programmable soft-start and shutdown capabilities

Applications

High-power LED lighting drivers
Industrial power supply systems
Battery charging applications requiring precise current control

Procurement Notes

Verify the specific suffix #PBF indicates lead-free tube packaging. Confirm RoHS compliance status through official manufacturer documentation. Ensure the supplier provides valid traceability data. Check for any obsolescence notices or limited availability warnings directly from Analog Devices before finalizing procurement plans.

Selection Notes

Select this component when designing synchronous buck converters requiring precise current regulation up to 20A. It is suitable for applications needing wide input voltage ranges and flexible switching frequencies. Consider the 20-TSSOP package constraints for thermal management and PCB layout requirements during the design phase.

Part Context

This part belongs to the LT3741 family of high-power controllers. It shares architectural similarities with the LT3741IFE but includes specific pin configurations or internal references defined by the '-1' designation. The series is designed for robust performance in demanding industrial and automotive environments.
