LTC3897EUHG-2#TRPBF

DC DC Switching Controllers Overview

The LTC3897EUHG-2#TRPBF is a PolyPhase synchronous boost DC/DC controller featuring input and output protection. It operates with an input voltage range of 4.5 V to 65 V and supports up to 10 A output current. The device utilizes a 38-WFQFN package with exposed pad. Switching frequency is adjustable from 75 kHz to 850 kHz, and the quiescent current is typically 55 uA. It functions within a temperature range of -40°C to +125°C.

DC DC Switching Controllers Feature Summary

• Integrates surge stopper and ideal diode controller for robust power path management
• Provides independent input and output overcurrent protection mechanisms
• Supports multi-phase operation via phase-lockable switching frequency

DC DC Switching Controllers Applications

• High-efficiency two-phase 48V boost converter designs
• Systems requiring reverse input protection
• Applications needing post-startup input supply reduction handling

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing. Confirm the manufacturer part number matches Analog Devices Inc. specifications exactly. Ensure the component meets RoHS compliance requirements for your assembly process. Check for any recent production change notices affecting the device.

DC DC Switching Controllers Selection Notes

Select this controller for applications requiring high input voltage tolerance up to 65 V. Consider the 38-pin QFN package for space-constrained layouts. Evaluate the need for integrated surge stopping versus external components. Verify that the adjustable frequency range suits the electromagnetic interference constraints of the system.

DC DC Switching Controllers Part Context

This component belongs to the LTC3897 family of synchronous boost controllers. It is designed for high-power density applications where efficiency and protection are critical. The device complements other PolyPhase controllers by offering specialized input and output safeguarding features not found in standard buck regulators.

DC DC Switching Controllers Replacement Considerations

LTC3897IUHG-2#PBF and LTC3897EUHG-2#PBF are related variants within the same family. Verify pin compatibility and thermal performance before substitution. Packaging differences may require re-evaluation of assembly processes.
