LT1107CS8#TRPBF

Overview

The LT1107CS8#TRPBF is a switching DC/DC converter manufactured by Analog Devices Inc., housed in an 8-SOIC package. It supports both Buck and Boost topologies with an input voltage range of 2 V to 30 V. The device provides a fixed 12 V output at up to 800 mA. Key electrical parameters include a 63 kHz switching frequency, 550 uA quiescent current, and operation within a temperature range of 0°C to +70°C.

Feature Summary

• Supports both step-down (Buck) and step-up (Boost) voltage conversion topologies
• Provides a fixed 12 V regulated output voltage
• Operates from a wide input voltage range starting at 2 V

Applications

• Battery-powered systems requiring voltage regulation
• General-purpose DC/DC conversion circuits
• Embedded power management designs

Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing components. Confirm that the CS8 variant corresponds to the commercial temperature grade of 0°C to +70°C for your application requirements. Ensure compatibility with the 8-SOIC footprint during PCB layout planning.

Selection Notes

Select this component when a fixed 12 V output is required from a variable or low input source. The integrated Buck-Boost capability allows flexibility for input voltages that may drop below or rise above the target output level. Consider the 800 mA output limit and 63 kHz switching frequency for filter component selection.

Part Context

This part belongs to the LT1107 series of switching regulators from Analog Devices. The series includes variants with different output voltages and packages. The CS8 designation specifies the commercial temperature range and SOIC-8 surface-mount package format used for this specific configuration.

Replacement Considerations

LT1107CS8-12#PBF: Identical functional specifications but supplied in tube packaging instead of tape-and-reel.
