LT1107CS8-12#TRPBF

Overview

The LT1107CS8-12#TRPBF is a micropower DC/DC converter manufactured by Analog Devices Inc., housed in an 8-SOIC surface-mount package. It provides a fixed 12V output with a maximum current of 800 mA. The device supports boost, buck, and inverting topologies, operating from a 2V to 30V input range. Key electrical parameters include a 63 kHz switching frequency, 550 uA static current, and operation within a 0°C to +70°C temperature range.

Feature Summary

• Versatile micropower DC/DC converter supporting step-up, step-down, and inverting applications
• Requires only three external components for fixed 5V or 12V output configurations
• Operates effectively across wide supply voltage ranges for diverse power management needs

Applications

• Palmtop computer logic power supplies
• Portable battery-powered equipment requiring efficient voltage conversion
• Systems utilizing single-cell alkaline or NiCd batteries

Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing. Confirm the fixed 12V output variant matches system requirements against adjustable models. Ensure compatibility with SOIC-8 footprint constraints during procurement planning.

Selection Notes

Select this component for designs needing a compact, low-component-count solution for 12V generation. Consider the 800 mA output limit and 63 kHz frequency for EMI-sensitive environments. Evaluate thermal performance within the specified industrial temperature range for reliable operation.

Part Context

This part belongs to the LT1107 series of micropower DC/DC converters. It shares the core architecture with variants like LT1107IS8#TRPBF but differs in fixed output voltage and packaging format. The series is designed for portable electronics where space and efficiency are critical.

Replacement Considerations

LT1107CS8-12#PBF offers identical electrical specifications in tube packaging instead of tape-and-reel.
