LT1371CSW#TRPBF

Overview

The LT1371CSW#TRPBF is a switching voltage regulator manufactured by Analog Devices Inc., housed in an SOIC-28 package. It operates with an input voltage range of 2.7 V to 30 V and delivers up to 3 A output current. The device supports multiple topologies including Boost, Buck, Cuk, Flyback, Forward, and Inverting configurations. It features an adjustable output voltage, a fixed switching frequency of 500 kHz, and a shutdown function. The component functions within a temperature range of 0°C to +125°C and draws 4 mA of static current.

Feature Summary

Supports versatile power conversion topologies including boost, buck, flyback, and inverting circuits
Integrates a high-efficiency 3 A switch for robust load handling
Includes a shutdown pin for power management control

Applications

Industrial power supply systems
Battery-powered equipment requiring step-up or step-down regulation
Telecommunications infrastructure power modules

Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing. Confirm the SOIC-28 package variant matches design requirements. Cross-reference the manufacturer part number LT1371CSW#TRPBF with official Analog Devices documentation to ensure authenticity and correct revision level before procurement.

Selection Notes

Select this component for designs requiring a single IC to support multiple converter topologies. Ensure the input voltage stays within the 2.7 V to 30 V range. Verify that the 500 kHz switching frequency aligns with EMI constraints and inductor size requirements. Check thermal performance for the SOIC-28 package under maximum load conditions.

Part Context

This part belongs to the LT1371 series of high-efficiency switching regulators from Analog Devices. It is designed as a flexible solution for various DC-DC conversion needs. The series is known for integrating the power switch and control logic into a single compact package to reduce external component count.
