Overview
The LT3741EUF#TRPBF is a synchronous step-down DC-DC controller IC from Analog Devices Inc., housed in a 20-WFQFN package. It operates with an input voltage range of 6 V to 36 V and supports output voltages from 4 V to 34 V. The device delivers up to 25 A of output current with a quiescent supply current of 1.8 mA. Switching frequency is adjustable between 200 kHz and 1 MHz. It functions within a temperature range of -40°C to +125°C TJ.
Feature Summary
- Synchronous rectification architecture for high efficiency
- Integrated soft-start and frequency control capabilities
- Clock synchronization support for multi-phase systems
- Shutdown pin for power management control
Applications
- High-power constant current battery charging systems
- Constant voltage power supply designs
- Industrial point-of-load regulation
- Automotive electronics power distribution
Procurement Notes
Verify the specific suffix #TRPBF indicates tape and reel packaging when ordering. Confirm that the component meets RoHS compliance standards required for your assembly process. Ensure the 20-QFN footprint matches your PCB layout guidelines. Check for any recent product change notices regarding assembly sites or material declarations before finalizing procurement.
Selection Notes
Select this controller for applications requiring high output current up to 25 A with precise voltage regulation. The wide input voltage range suits various bus architectures. Consider the thermal performance of the QFN package for heat dissipation requirements. Evaluate the need for clock synchronization if operating in parallel configurations.
Part Context
This part belongs to the LT3741 family of high-performance buck controllers. It is designed for demanding applications requiring robust power management. The device integrates essential features for efficient energy conversion. It complements other PMIC solutions from Analog Devices Inc. for complete system power design.
Replacement Considerations
LT3741EUF#PBF offers the same electrical specifications but in tube packaging instead of tape and reel. LT3741IFE-1#PBF provides equivalent functionality in a TSSOP package. Verify pinout compatibility and thermal characteristics when substituting packages.
