LT1111IS8#TRPBF

Overview

The LT1111IS8#TRPBF is a micropower DC/DC converter manufactured by Analog Devices Inc., housed in an 8-SOIC package. It supports both buck and boost topologies with an adjustable output voltage ranging from 1.25V to 50V. The device operates within an input voltage range of 2V to 30V, delivering a switch current of 1.5A. It features a fixed switching frequency of 72kHz and a typical quiescent current of 300uA. The component functions across a temperature range of -40°C to +85°C.

Feature Summary

Supports both step-down (buck) and step-up (boost) conversion modes for flexible power management
Provides adjustable output voltage capability covering positive and negative configurations
Integrates a high-current internal switch rated at 1.5A for robust load handling

Applications

Battery-powered systems requiring voltage regulation across varying charge levels
Portable equipment utilizing single-cell or multi-cell battery inputs
Industrial control circuits needing isolated or non-isolated DC-DC conversion

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 (-40°C to +85°C) required for your application environment. Ensure compatibility with the 8-SOIC footprint during PCB layout validation.

Selection Notes

Select this component when design requirements demand a single IC solution capable of handling both input voltages higher and lower than the target output. The 1.5A switch current rating allows for moderate load applications without external pass transistors. Consider the 72kHz switching frequency for balancing component size and efficiency needs.

Part Context

This part belongs to the LT1111 series of micropower DC/DC converters from Analog Devices. It shares core topology and performance characteristics with other variants in the family, such as the LT1111CS8, differing primarily in temperature range specifications and packaging options like tube versus reel.
