LT1374HVCS8#TRPBF

Overview

The LT1374HVCS8#TRPBF is a monolithic Buck/SEPIC switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 5V to 32V and provides an adjustable output voltage from 2.42V to 27.52V. The device supports a switch current of 4.5A and features a fixed switching frequency of 500kHz. It utilizes current-mode control and includes shutdown functionality. The component is housed in an 8-SOIC package (0.154 inch width) and is rated for operation between -40°C and +125°C.

Feature Summary

Supports both Buck and SEPIC topologies for flexible power conversion
Integrates a 4.5A internal switch for high current capability
Features low quiescent current for improved efficiency
Includes thermal shutdown protection

Applications

Industrial distributed power systems
Battery-powered equipment requiring step-down or boost regulation
Telecommunications infrastructure power supplies
Automotive electronics operating within specified voltage ranges

Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when ordering. Confirm the HV variant requirements against standard LT1374 specifications, as the HV version supports higher input voltages up to 32V. Ensure the SOIC-8 package dimensions match your PCB footprint design constraints before finalizing procurement.

Selection Notes

Select this component when designing circuits that require either Buck or SEPIC topology within a single IC solution. The 4.5A switch rating suits applications needing moderate to high output currents. Consider the 500kHz switching frequency for balancing component size and efficiency. Verify that the 32V maximum input voltage aligns with your system's supply rails.

Part Context

This part belongs to the LT1374 family of switching regulators, which are known for combining high performance with compact solutions. The LT1374 series offers versatility through its ability to function as both a Buck and SEPIC converter. The HV designation specifically denotes enhanced input voltage capabilities compared to standard variants.
