LT1376IS

Overview

The LT1376IS is a monolithic buck mode switching regulator manufactured by Analog Devices. It integrates a 1.5A power switch, oscillator, and control logic within an 8-pin SOIC package. The device operates with an input voltage range of 5V to 25V and delivers a fixed 5V output at up to 1.5A. It functions at a 500kHz switching frequency, enabling the use of small external components. Quiescent current is 20µA, with a shutdown feature reducing consumption further. Operating temperature spans -40°C to +125°C.

Feature Summary

Integrates a 1.5A power switch and control circuitry for compact design
High 500kHz switching frequency reduces external component size
Includes shutdown capability for low standby power consumption

Applications

Battery-powered systems requiring efficient step-down conversion
Post-regulation for bus distribution networks
General-purpose DC-DC conversion in industrial equipment

Procurement Notes

Verify the specific suffix (e.g., IS vs IS#PBF) against the manufacturer's official datasheet to confirm lead-free compliance and marking details. Ensure the package type matches the PCB footprint requirements. Confirm availability status through authorized distributors as supply levels may vary.

Selection Notes

Select this component when a fixed 5V output is required from a 5V to 25V input source. It is suitable for applications needing 1.5A continuous current with minimal external parts. Consider thermal performance in the SOIC-8 package for high ambient temperatures or high load currents.

Part Context

The LT1376 belongs to the LT137x family of high-frequency buck regulators. It shares architectural similarities with the LT1375 but offers a fixed output voltage option instead of adjustable. This series targets applications prioritizing board space efficiency and simplicity over synchronous rectification efficiency.
