LT1376CS8#TRPBF

Overview

The LT1376CS8#TRPBF is a synchronous step-down switching regulator manufactured by Analog Devices Inc. It operates within an input voltage range of 5 V to 25 V and delivers a maximum output current of 1.5 A. The device features a fixed switching frequency of 500 kHz and supports adjustable output voltages. It is housed in an SOIC-8 surface-mount package and includes a shutdown function for power management. The component functions as a buck converter with a quiescent operating supply current of 2.5 mA.

Feature Summary

• Integrates high-side and low-side power switches for efficient synchronous rectification
• Supports multiple topologies including Buck, SEPIC, and Flyback configurations
• Includes a dedicated shutdown pin for active low-power control

Applications

• Battery-powered portable equipment
• Distributed power systems
• Post-regulation after bus converters

Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing components. Confirm that the SOIC-8 package matches the target PCB footprint requirements. Ensure the supplier provides valid RoHS compliance documentation consistent with Analog Devices standards. Cross-reference the manufacturer part number against official distributor catalogs to avoid counterfeit inventory risks.

Selection Notes

Select this regulator for designs requiring a 1.5 A output capability from a 5 V to 25 V input range. The 500 kHz switching frequency allows for smaller external passive components compared to lower-frequency alternatives. Consider the thermal performance of the SOIC-8 package for the expected load conditions. Verify that the adjustable output voltage range meets the specific system rail requirements.

Part Context

This component belongs to the LT1376 series of high-efficiency switching regulators. It is designed for applications demanding compact solutions with robust current handling capabilities. The series supports various converter topologies beyond standard buck configurations, offering design flexibility for different power architecture needs.

Replacement Considerations
