LT1374IFE

Overview

The LT1374IFE is a monolithic buck switching regulator manufactured by Analog Devices. It integrates a 4.5A power switch, oscillator, and control logic in a 16-pin TSSOP-EP package. The device operates at a fixed 500kHz frequency with an input voltage range of 5V to 32V. It provides adjustable output voltage and supports up to 3.6A continuous output current. Key electrical parameters include a typical quiescent current of 20µA in shutdown mode and 2.5mA during operation. The unit features cycle-by-cycle current limiting and is rated for operation between -40°C and +125°C.

Feature Summary

Integrates a high-efficiency 4.5A power switch with low on-resistance
Supports external synchronization via the SYNC pin for noise-sensitive applications
Offers precise shutdown control with ultra-low standby current consumption
Utilizes current-mode control architecture for fast transient response

Applications

High-density point-of-load regulation
Battery-powered portable equipment
Industrial control systems
Communication infrastructure power supplies

Procurement Notes

Verify the specific suffix against official documentation to confirm package type and temperature grade. Ensure compatibility with required input voltage ranges and thermal management solutions. Confirm RoHS compliance status through manufacturer datasheets before integration into final designs.

Selection Notes

Select this component for applications requiring high current density in surface-mount formats. The TSSOP-EP package facilitates efficient heat dissipation compared to standard variants. Consider the extended input voltage capability when designing for automotive or industrial bus architectures.

Part Context

This part belongs to the LT1374 family of step-down switching regulators. It shares core topology and performance characteristics with other members like the LT1374CT7 and LT1374CR, differing primarily in package configuration and thermal handling capabilities suitable for various PCB layout constraints.
