LT1377CS8#TRPBF

Overview

The LT1377CS8#TRPBF is a high-efficiency switching regulator from Analog Devices, operating at a fixed 1 MHz switching frequency. It supports multiple topologies including Boost, Buck, Cuk, Flyback, Forward, and Inverting configurations. The device accepts an input voltage range of 2.7 V to 25 V and delivers up to 1.5 A output current with adjustable output voltage. It features a low quiescent current of 4 mA and includes shutdown functionality. Operating temperatures range from 0°C to +125°C in an SOIC-8 surface-mount package.

Feature Summary

Supports versatile circuit topologies including boost, buck, cuk, flyback, forward, and inverting configurations
Integrates a high-efficiency 1.5 A power switch for robust current handling
Enables system power management through dedicated shutdown control

Applications

Portable battery-powered equipment requiring flexible voltage conversion
Industrial systems utilizing standard 5V or 12V supply rails
Telecommunications infrastructure power distribution networks

Procurement Notes

Verify the specific suffix against official documentation to confirm tape-and-reel packaging versus tube variants. Confirm RoHS compliance status and lead-free manufacturing details directly with the manufacturer. Ensure the selected component matches the required thermal performance specifications for the intended application environment before finalizing procurement orders.

Selection Notes

Select this component when design requirements demand a single IC solution capable of supporting diverse converter topologies. The 1 MHz frequency allows for smaller passive components compared to lower-frequency alternatives. Verify that the input voltage range aligns with the source supply and that the 1.5 A current rating meets peak load demands without exceeding thermal limits.

Part Context

This part belongs to the LT1377 family of high-efficiency switching regulators. It shares core architectural similarities with the LT1376 but offers broader topology support. The CS8 designation indicates commercial temperature range operation in an SOIC-8 package. The #TRPBF suffix specifies the tape-and-reel packaging format for automated assembly processes.
