LT1374IR-5#PBF

Overview

The LT1374IR-5#PBF is a monolithic buck switching regulator manufactured by Analog Devices Inc. It operates with a fixed 500 kHz switching frequency and accepts an input voltage range of 5 V to 25 V. The device provides a fixed 5 V output capable of delivering up to 3.6 A of continuous current. It features a low quiescent current of 20 uA and operates within a temperature range of -40°C to +125°C. The component is housed in a DDPAK-7 surface-mount package.

Feature Summary

Integrates a constant 500 kHz switching frequency to minimize external inductor size
Provides high power density through a compact 16-pin TSSOP or DDPAK package option
Utilizes all surface mount components for simplified assembly
Includes shutdown functionality for power management

Applications

Point-of-load regulation for digital signal processors
Power supply stages for embedded systems
Industrial control system voltage regulation

Procurement Notes

Verify the specific suffix and package type against the official datasheet, as variations exist within the LT1374 family. Confirm that the IR designation matches the required industrial temperature range and DDPAK-7 packaging. Ensure compatibility with the target PCB footprint before finalizing procurement orders.

Selection Notes

Select this part when a fixed 5 V output is required from a 5 V to 25 V input source. It is suitable for applications needing moderate current delivery with reduced passive component count due to the high switching frequency. Consider thermal performance requirements given the DDPAK-7 package constraints under full load conditions.

Part Context

This component belongs to the LT1374 series of step-down switching regulators. The series is characterized by its ability to drive high currents while maintaining efficiency at high frequencies. The LT1374IR-5#PBF specifically denotes the fixed 5 V output variant in the industrial temperature grade.
