LT1374IR#TRPBF

Overview

The LT1374IR#TRPBF is a monolithic buck switching regulator manufactured by Analog Devices Inc. It operates with a fixed 500 kHz switching frequency and supports an input voltage range from 5 V to 25 V. The device delivers up to 4.5 A of switch current, providing regulated outputs at 5 V or adjustable voltages down to 2.48 V depending on the specific suffix configuration. It features low quiescent current of 20 uA and operates within a temperature range of -40°C to +125°C. Packaged in a 7-pin DDPAK surface-mount format, it integrates current-mode control for stable performance.

Feature Summary

Integrates current-mode control architecture for precise regulation
Supports wide input voltage ranges suitable for various power rails
Incorporates shutdown functionality for enhanced power management
Features low static current consumption for efficiency optimization

Applications

Point-of-load regulation in industrial systems
Power supply stages for embedded computing platforms
Battery-powered equipment requiring efficient step-down conversion
General-purpose DC-DC conversion in telecommunications infrastructure

Procurement Notes

Verify the exact suffix against official Analog Devices documentation to confirm output voltage configuration and package type. Cross-reference datasheet specifications for thermal performance requirements under expected load conditions. Ensure compatibility with PCB footprint dimensions specified in the mechanical drawings prior to integration.

Selection Notes

Evaluate thermal dissipation capabilities based on ambient temperature and load current requirements. Compare input voltage stability against the specified 5 V minimum threshold. Assess component availability and lead times through authorized distributors. Confirm regulatory compliance status including RoHS and REACH directives for target markets.

Part Context

This component belongs to the LT1374 series of high-current switching regulators designed for demanding applications. It represents a legacy product line from Linear Technology, now part of Analog Devices. The series is known for robust performance in space-constrained designs requiring significant current delivery without external feedback complexity.
