LT1374IS8#TRPBF

Overview

The LT1374IS8#TRPBF is a monolithic buck switching regulator manufactured by Analog Devices Inc. It integrates a 4.5A power switch and operates at a constant 500kHz frequency. The device supports an input voltage range of 5V to 25V with an adjustable output voltage. Key electrical specifications include a maximum output current of 4.5A, a typical supply current of 2.5mA, and a shutdown current of 20µA. It features cycle-by-cycle current limiting and is housed in an 8-lead SOIC package.

Feature Summary

Integrates a high-current 4.5A power switch for efficient step-down conversion
Maintains a fixed 500kHz switching frequency to minimize external component size
Includes built-in cycle-by-cycle current limiting for robust protection

Applications

Point-of-load regulation for embedded systems
Battery-powered equipment requiring efficient DC-DC conversion
General-purpose step-down power supplies

Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing. Confirm the IS8 variant meets industrial temperature requirements if applicable. Ensure compatibility with the 8-SOIC footprint during PCB layout. Cross-reference official datasheets for exact pinout and thermal characteristics before finalizing procurement orders.

Selection Notes

Select this component for designs requiring high output current up to 4.5A from a moderate input voltage range. The fixed 500kHz frequency allows for smaller inductors compared to lower-frequency regulators. Consider the 2.5mA supply current for efficiency calculations under load. Verify that the 25V maximum input voltage aligns with the system's power source constraints.

Part Context

This part belongs to the LT1374 series of monolithic buck regulators. It shares functional similarities with other members like the LT1374HV but differs in input voltage capabilities. The series is designed for applications needing compact solutions with high current density. It complements Analog Devices' portfolio of synchronous and non-synchronous switching regulators.
