LT1111IS8#PBF

Overview

The LT1111IS8#PBF is a synchronous step-down/step-up switching regulator IC manufactured by Analog Devices Inc. It operates with an input voltage range of 2V to 30V and provides a fixed output voltage of 1.25V. The device supports a maximum switch current of 1.5A and functions at a switching frequency of 72kHz. Designed for surface-mount installation in an 8-SOIC package, it delivers positive or negative output configurations. The component is rated for an operating temperature range from -40°C to +105°C.

Feature Summary

Integrated synchronous rectification for improved efficiency
Capable of buck and boost topologies
Supports positive or negative output configurations

Applications

Portable battery-powered equipment
Automotive electronics systems
Industrial control circuits

Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance when sourcing. Confirm the manufacturer part number matches exactly to ensure correct pinout and electrical characteristics. Check official documentation for any recent product change notices that may affect marking or specifications before finalizing procurement orders.

Selection Notes

Select this component when a fixed 1.25V output is required from a wide input voltage range. Ensure the application demands a synchronous topology for higher efficiency compared to non-synchronous alternatives. Verify that the 1.5A switch current rating meets the peak load requirements of the target circuit design.

Part Context

This part belongs to the LT1111 series of switching regulators. It shares the same core functionality as the LT1111CS8#PBF but differs in the specified industrial temperature range. Both variants utilize the 8-SOIC package and support identical buck-boost operations within the same electrical parameters.
