LT1107IS8#TRPBF

Overview

The LT1107IS8#TRPBF is a switching voltage regulator IC from Analog Devices, packaged in an 8-SOIC surface-mount format. It functions as a buck-boost DC/DC converter capable of providing positive or negative adjustable output voltages starting from 1.25V up to 50V at the switch node. The device supports a maximum switch current of 1.5A and operates with an input voltage range of 2V to 30V. It utilizes a fixed switching frequency of 63kHz and features an industrial operating temperature range spanning from -45°C to +85°C.

Feature Summary

Supports both step-down (buck) and step-up (boost) topologies for flexible power conversion
Provides single output configuration with adjustable voltage control
Capable of generating either positive or negative output polarities

Applications

Battery-powered systems requiring voltage regulation across varying charge levels
Industrial control circuits needing isolated or inverted power rails
Portable instrumentation utilizing single-cell battery sources

Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing components. Confirm that the IS8 designation corresponds to the industrial temperature grade (-45°C to +85°C) required for your application environment. Ensure compatibility with the 8-SOIC footprint during PCB layout verification.

Selection Notes

Select this component when designing circuits that require bidirectional voltage conversion from a single supply source. It is suitable for applications where input voltage may fluctuate above or below the desired output level. Consider the 1.5A switch current limit and external inductor requirements when sizing passive components for the target load.

Part Context

This part belongs to the LT1107 series of monolithic switching regulators. It shares the core topology with variants like the LT1107CS8-12#PBF but differs in package type and temperature rating. The IS8 variant specifically targets industrial environments compared to commercial grade alternatives within the same functional family.
