LT1108CS8-12#TRPBF

Overview

The LT1108CS8-12#TRPBF is a micropower DC/DC converter in an 8-pin SOIC package. It provides a fixed 12V output with a maximum current of 0.4A. The input voltage range spans from 2V to 30V, supporting step-up, step-down, and inverting topologies. Operating at a switching frequency of 19kHz, it draws 110uA of quiescent current. The device functions within a temperature range of 0°C to +70°C.

Feature Summary

• Versatile topology supporting step-up, step-down, and inverting configurations
• Micropower operation with low quiescent current consumption
• Fixed 12V output capability requiring minimal external components

Applications

• 5V to -5V conversion circuits
• Palmtop computer logic power supplies
• 6.5V to 20V step-down applications

Procurement Notes

Verify the suffix #TRPBF indicates tape-and-reel packaging distinct from tube variants. Confirm the manufacturer is Analog Devices Inc. Ensure the part number matches the specific 12V fixed output requirement. Check RoHS compliance status via official documentation before procurement.

Selection Notes

Select this component for applications requiring a fixed 12V output from variable inputs between 2V and 30V. It suits designs needing buck, boost, or inverting functionality without shutdown control. Consider the 19kHz switching frequency and 0.4A current limit for load requirements.

Part Context

This part belongs to the LT1108 series of versatile micropower DC/DC converters. It shares core architecture with other variants like LT1108CN8-12 but differs in package type and reel configuration. The series is designed for efficient power conversion using only four external components.

Replacement Considerations

LT1108CS8-12#PBF is a compatible tube-packaged alternative.
