LT1374IFE#TRPBF

Overview

The LT1374IFE#TRPBF is a monolithic buck switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 5 V to 25 V and delivers up to 4.5 A of output current. The device features a fixed 500 kHz switching frequency and supports adjustable output voltages. It utilizes current-mode control architecture for rapid transient response. The component is housed in a 16-lead TSSOP package with an exposed pad and functions within a temperature range of -40°C to +125°C.

Feature Summary

Integrates high-current power switch capable of delivering 4.5 A continuous load current
Employs current-mode control architecture for fast line and load transient response
Includes internal compensation network to minimize external component count
Features thermal shutdown protection to safeguard the device under overload conditions

Applications

Point-of-load regulation for digital signal processors
Power supply stages for embedded systems and industrial controllers
Battery-powered equipment requiring efficient step-down conversion
Telecommunications infrastructure power distribution networks

Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging configuration. Confirm the IFE variant corresponds to the extended industrial temperature range specifications. Ensure compatibility with the target PCB footprint for the 16-TSSOP-EP package. Cross-reference the manufacturer datasheet for exact pinout assignments and recommended external component values before finalizing procurement orders.

Selection Notes

Select this component when designing systems requiring high efficiency at moderate currents without complex external compensation. The fixed 500 kHz frequency allows for smaller passive components compared to lower-frequency alternatives. Consider the thermal performance of the TSSOP-EP package for heat dissipation requirements. Evaluate input voltage stability against the specified 5 V minimum threshold during startup conditions.

Part Context

This part belongs to the LT1374 family of high-current step-down regulators designed for robust performance in demanding environments. The series offers a balance of power density and ease of implementation through integrated control logic. It serves as a core power management solution for applications needing reliable DC-DC conversion from standard bus voltages.
