LT1173CS8-12#TRPBF

Overview

The LT1173CS8-12#TRPBF is a micropower DC/DC converter manufactured by Analog Devices Inc., housed in an 8-SOIC surface-mount package. It operates as a fixed-output regulator providing 12V at up to 800mA. The device supports Buck, Boost, and Inverting topologies with an input voltage range of 2V to 30V. Key electrical parameters include a switching frequency of 23kHz, a maximum quiescent current of 110uA, and an operating temperature range from 0°C to +70°C.

Feature Summary

Supports versatile step-up, step-down, and inverting configurations using minimal external components.
Delivers high output current capability relative to its low power consumption profile.
Operates efficiently across a wide input voltage range suitable for battery-powered applications.

Applications

Portable instrumentation powered by single-cell or multi-cell batteries
Battery-operated systems requiring stable voltage regulation
General-purpose DC/DC conversion in space-constrained designs

Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing. Confirm the fixed 12V output variant matches system requirements. Check manufacturer documentation for RoHS compliance status and lead times. Ensure compatibility with standard SOIC-8 footprint during PCB layout.

Selection Notes

Select this component for applications requiring flexible topology options including buck, boost, and inverting modes. Consider the 23kHz switching frequency for EMI management and component sizing. Evaluate the 800mA output current against peak load demands. Verify that the 0°C to +70°C industrial temperature range meets environmental specifications.

Part Context

This part belongs to the LT1173 series of micropower DC/DC converters from Analog Devices. The series is known for enabling simple designs with few external components while supporting multiple conversion topologies. The CS8 suffix denotes the SOIC-8 package, and the -12 specifies the fixed 12V output version.
