LT1374IFE#PBF

Overview

The LT1374IFE#PBF is a monolithic buck switching regulator manufactured by Analog Devices Inc. It integrates a 4.5A power switch and operates at a fixed 500kHz frequency. The device supports an input voltage range of 5V to 32V with an adjustable output voltage starting from 2.42V. It features a low quiescent current of 2.5mA and a shutdown current of 20µA. The component is housed in a 16-lead TSSOP package with an exposed pad, suitable for surface mount applications across a temperature range of -40°C to +125°C.

Feature Summary

Integrates a high-current 4.5A internal power switch for efficient step-down conversion
Supports cycle-by-cycle current limiting and easy synchronization capabilities
Features low standby consumption with dedicated shutdown control functionality

Applications

Point-of-load regulation for industrial equipment
Power supply stages for battery-operated systems
General-purpose DC/DC conversion in embedded electronics

Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm pinout compatibility and thermal performance requirements. Ensure the selected package variant matches the intended PCB layout constraints. Cross-reference the datasheet revision history to validate electrical characteristics for the specific manufacturing batch.

Selection Notes

Select this component when a fixed 500kHz operation is required to minimize external passive component size. The wide input voltage range accommodates various supply rails without additional pre-regulation. Consider the thermal dissipation capabilities of the TSSOP-EP package for high-load continuous duty cycles.

Part Context

This part belongs to the LT1374 family of high-efficiency step-down regulators. It shares core architecture with variants like the LT1374HVIFE#PBF but differs in package configuration and specific thermal ratings. The series is designed for applications requiring compact solutions with high power density.
