LT3741EFE#TRPBF

Overview

The LT3741EFE#TRPBF is a synchronous step-down DC/DC controller manufactured by Analog Devices Inc. It operates with an input voltage range of 6V to 36V and supports output voltages from 0V to 34V. The device regulates output current up to 20A at switching frequencies between 200kHz and 1MHz. It features a 20-lead TSSOP package with exposed pad, suitable for surface mount applications. The controller includes soft start, frequency control, and shutdown capabilities, operating within a temperature range of -40°C to +125°C.

Feature Summary

Synchronous buck topology for high-efficiency power conversion
Integrated constant current regulation for battery charging applications
Programmable switching frequency allows optimization for size and efficiency
Built-in soft start minimizes inrush current during startup

Applications

Battery chargers for portable devices
High-power LED drivers
Point-of-load regulation modules
Industrial power supply systems

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when ordering. Confirm that the EFE variant corresponds to the TSSOP-20 package type required for your PCB layout. Ensure compatibility with the intended switching frequency settings and thermal management requirements for the target application environment before finalizing procurement.

Selection Notes

Select this component when a synchronous buck controller with precise current regulation is needed for inputs up to 36V. The 20A capability suits medium-to-high power loads. Consider the TSSOP-20 package constraints and the need for external MOSFETs and inductors. Evaluate thermal performance needs given the 125°C junction temperature rating.

Part Context

The LT3741 series belongs to Analog Devices' family of high-performance synchronous step-down controllers. This specific part is designed for applications requiring accurate current control alongside voltage regulation. It complements other PMIC solutions by offering dedicated features for battery charging and LED driving scenarios within the same product line.
