LTC3854EDDB#TRPBF

DC DC Switching Controllers Overview

The LTC3854EDDB#TRPBF is a synchronous step-down switching regulator controller from Analog Devices. It operates with an input voltage range of 4.5V to 38V and provides an adjustable output voltage between 0.8V and 5.5V. The device supports up to 25A of output current using a fixed-frequency peak current mode topology at a switch frequency of 400kHz. It features low quiescent current of 15µA and includes DCR current sensing capabilities. The component is housed in a compact 2mm x 3mm DFN-8 package.

DC DC Switching Controllers Feature Summary

Integrates N-channel FET gate drivers for high-efficiency synchronous buck conversion
Supports DC resistance (DCR) current sensing to eliminate sense resistors and improve efficiency
Provides precise cycle-by-cycle peak current limiting via fixed-frequency operation
Features low static current consumption for enhanced power management

DC DC Switching Controllers Applications

Automotive electronics systems requiring wide input voltage tolerance
Industrial control equipment and power distribution units
Telecommunications infrastructure and base station power supplies

DC DC Switching Controllers Procurement Notes

Verify the specific suffix TRPBF indicates tape and reel packaging configuration. Confirm RoHS compliance status through official documentation. Ensure the DFN-8 package dimensions match the design constraints. Check for any recent product change notices regarding manufacturing location or materials. Validate availability status as supply conditions may vary by region.

DC DC Switching Controllers Selection Notes

Select this controller when a small footprint and wide input voltage range are critical. The integrated gate drivers reduce external component count compared to discrete solutions. Consider the 400kHz switching frequency for balancing efficiency and transient response. Verify that the target application requires peak current mode control and DCR sensing compatibility.

DC DC Switching Controllers Part Context

This component belongs to the LTC3854 family of synchronous buck controllers designed for space-constrained applications. It complements other Analog Devices power management solutions by offering high current capability in a minimal package size. The device is part of the broader portfolio aimed at automotive and industrial sectors.
