LT1375IS8#TRPBF

Overview

The LT1375IS8#TRPBF is a monolithic buck mode switching regulator manufactured by Analog Devices Inc. It integrates a 1.5A power switch, oscillator, control circuitry, and logic into an 8-lead SOIC package. The device operates with an input voltage range of 5V to 25V and provides a fixed 5V output at up to 1.2A. It functions at a 500kHz switching frequency, enabling the use of small external components. The part supports shutdown functionality and operates within a temperature range of -40°C to +125°C.

Feature Summary

• Integrates a high-current 1.5A power switch for efficient step-down conversion
• High 500kHz switching frequency reduces required external component size
• Includes complete oscillator, control, and logic circuitry on a single die
• Supports shutdown mode for enhanced power management

Applications

• Point-of-load regulation in industrial systems
• Power supply stages for embedded controllers
• Battery-powered equipment requiring efficient voltage stepping

Procurement Notes

Verify the specific suffix against official documentation to confirm tape-and-reel packaging versus tube variants. Confirm RoHS compliance status through current manufacturer declarations. Ensure the operating temperature range meets system requirements. Cross-reference the exact part number with Analog Devices to avoid confusion with similar LT1375 family members.

Selection Notes

Select this component when a robust 1.5A buck converter is needed with minimal external parts. The 500kHz frequency balances efficiency and component size effectively. Verify that the 5V fixed output aligns with load requirements. Consider thermal performance in the SOIC-8 package under maximum load conditions.

Part Context

This part belongs to the LT1375 series of monolithic switching regulators. It shares architectural similarities with other devices in the family but is distinguished by its specific output configuration and packaging. The series is designed for applications requiring high efficiency and compact form factors in DC-DC conversion tasks.
