Overview
The LT1375HVIS8#TRPBF is a monolithic Buck/SEPIC switching regulator from Analog Devices. It integrates a 1.5A switch and operates at a fixed 500kHz frequency. The device accepts an input voltage range of 5V to 30V and provides a positive adjustable output starting from 2.42V. It features low quiescent current of 20µA and supports shutdown mode. Operating temperatures range from -40°C to +125°C, housed in an 8-SOIC package.
Feature Summary
- Integrated 1.5A power switch for compact design
- Supports both Buck and SEPIC topologies
- Low standby current consumption
- Fixed high-frequency operation for small external components
Applications
- Industrial embedded power systems
- Battery-powered equipment requiring efficient step-down conversion
- Systems needing SEPIC capability for varying input voltages
Procurement Notes
Verify the specific suffix TRPBF indicates tape and reel packaging when ordering. Confirm the VIS8 variant meets thermal requirements for your application. Ensure compatibility with 8-SOIC footprint during PCB layout. Check latest datasheet for any pinout revisions or updated electrical limits before finalizing procurement.
Selection Notes
Select this component when a combined Buck/SEPIC solution is required without external synchronous rectifiers. The 500kHz frequency allows for smaller inductors compared to lower-frequency alternatives. Consider the 1.5A limit for load requirements. The wide input range suits applications with variable source voltages.
Part Context
This part belongs to the LT1375/LT1376 family of monolithic switching regulators. These devices are designed for high-efficiency DC-DC conversion. The family shares core architecture but varies in current ratings and package options. The LT1375 specifically targets applications needing moderate current with flexible topology support.
Replacement Considerations
LT1375HVIS8#TR: Same function in tube packaging instead of tape and reel. LT1375HVIS8#PBF: Non-lead-free version in tube packaging. Verify RoHS compliance requirements if substituting with non-PBF variants.
