LT1371IR#PBF

Overview

The LT1371IR#PBF is a high-efficiency switching regulator manufactured by Analog Devices Inc., housed in a DDPAK-7 surface-mount package. It operates with an input voltage range of 2.7 V to 25 V and delivers up to 3 A of output current. The device supports multiple topologies including Boost, Buck, Cuk, Flyback, Forward, and Inverting configurations. It features an adjustable output voltage and a fixed switching frequency of 500 kHz. The unit functions within a temperature range of -40°C to +125°C and includes a shutdown feature.

Feature Summary

Supports versatile DC/DC conversion topologies such as boost, buck, flyback, and inverting circuits
Integrates a high-efficiency power switch capable of delivering 3 A continuous output current
Includes a dedicated shutdown pin for precise power management control

Applications

Portable battery-powered equipment requiring efficient step-up or step-down regulation
Industrial systems utilizing flyback or forward converter architectures
Negative voltage generation applications using inverting topology

Procurement Notes

Verify the specific suffix 'IR' indicates the industrial temperature grade (-40°C to +125°C) compared to commercial variants. Confirm the DDPAK-7 package type matches your thermal design requirements. Ensure the '#PBF' designation confirms lead-free compliance and RoHS standards before finalizing procurement orders.

Selection Notes

Select this component when a single IC must support multiple converter topologies without external controller complexity. The 500 kHz frequency allows for compact passive components. Consider the 3 A current limit for moderate power loads. Verify that the 2.7 V minimum input voltage aligns with your source supply characteristics.

Part Context

This part belongs to the LT1371 family of monolithic switching regulators from Analog Devices. It shares functional similarities with the LT1370 but offers lower current capability. The series is designed for applications needing flexible topology implementation in a small footprint.
