LT1374CS8-5SYNC#TRPBF

Overview

The LT1374CS8-5SYNC#TRPBF is a monolithic buck switching regulator manufactured by Analog Devices Inc. It operates with a fixed 5V output and supports an input voltage range from 5V to 25V. The device delivers a typical output current of 3.6A with a switch current limit of 4.5A. It functions at a fixed switching frequency of 500kHz. Key electrical parameters include a maximum operating temperature of +125°C, a minimum of 0°C, and a quiescent current of 20µA. The component is housed in an 8-SOIC package.

Feature Summary

Integrates high-speed power MOSFETs for efficient step-down conversion
Features synchronous rectification control for improved efficiency
Includes internal compensation to minimize external component count
Provides thermal shutdown protection for system reliability

Applications

Point-of-load regulation for digital signal processors
Power supply stages for embedded communication systems
Battery-powered equipment requiring efficient voltage stepping
Industrial control modules needing stable 5V rails

Procurement Notes

Verify the specific suffix SYNC#TRPBF against official Analog Devices documentation to confirm tape-and-reel packaging and synchronization capabilities. Ensure the ordering part number matches the required fixed 5V output variant. Cross-reference datasheet revisions to validate pinout compatibility and electrical specifications before finalizing procurement orders.

Selection Notes

Select this component when a fixed 5V output is required without external feedback resistors. It is suitable for designs prioritizing high efficiency through synchronous operation at 500kHz. Consider the 8-SOIC package constraints and thermal performance limits. Verify that the input voltage range of 5V to 25V aligns with the system power source requirements.

Part Context

This part belongs to the LT1374 family of high-current switching regulators. It shares the core topology with adjustable variants like the LT1374HVCS8#PBF but provides a fixed 5V output. The SYNC suffix indicates synchronization capability, distinguishing it from standard asynchronous versions within the same package footprint.
