LT1173CS8-5#PBF

Overview

The LT1173CS8-5#PBF is a micro-power DC-DC switching regulator manufactured by Analog Devices. It operates in boost, buck, or inverting topologies with an input voltage range of 2V to 30V. The device delivers a fixed 5V output at up to 800mA. Key electrical parameters include a typical quiescent current of 110µA and a switching frequency of 23kHz. It functions effectively as a step-up converter with inputs from 2V to 12V, or as a step-down converter with inputs up to 30V.

Feature Summary

Versatile topology support for step-up, step-down, and inverting configurations
Micro-power operation with low static current consumption
Fixed output voltage options including 5V and 12V
Wide input voltage capability ranging from 2V to 30V

Applications

Logic controlled flash memory VPP generators
High power low quiescent current step-down converters
General purpose micro-power DC-DC conversion
Positive to negative voltage inversion circuits

Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and tube packaging when sourcing. Confirm the manufacturer is Analog Devices Inc., formerly Linear Technology. Ensure the SOIC-8 package matches your PCB footprint requirements. Check RoHS status and moisture sensitivity level before assembly. Validate that the fixed 5V output variant meets your system voltage needs.

Selection Notes

Select this component for applications requiring a simple three-component solution for micro-power conversion. It is suitable for battery-powered systems due to low quiescent current. Choose this part if you need flexibility between step-up and step-down modes within a single IC. Consider the 23kHz switching frequency for EMI-sensitive designs compared to higher frequency alternatives.

Part Context

This part belongs to the LT1173 series of versatile micro-power DC-DC converters. It is designed to replace discrete transistor solutions with a single integrated circuit. The series supports multiple topologies, making it a flexible choice for various power management tasks in portable and industrial electronics.
