LT1173CS8#PBF

Overview

The LT1173CS8#PBF is a versatile micro-power DC-DC converter manufactured by Analog Devices Inc. It supports boost, buck, and inverting topologies within an 8-SOIC package. The device operates with an input voltage range of 2 V to 30 V and delivers up to 800 mA output current. Key electrical parameters include a fixed 5 V or 12 V output option, adjustable output capability, and a switching frequency of 23 kHz. Quiescent current is specified at 110 uA typical, with a maximum operating temperature of +70 C.

Feature Summary

Supports multiple conversion modes including step-up, step-down, and inverting configurations.
Requires only three external components for fixed output implementations.
Operates effectively across wide input voltage ranges suitable for various power sources.

Applications

Telecommunications power supply circuits
LCD bias generation requiring negative voltage outputs
Battery-powered systems utilizing alkaline cells

Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance when sourcing. Confirm the SOIC-8 package dimensions match your PCB footprint requirements. Ensure the operating temperature range aligns with your environmental specifications. Check for any recent product change notices regarding pinout or electrical characteristics before finalizing design integration.

Selection Notes

Choose this component for applications requiring flexible topology selection from a single IC. It is suitable for designs needing low quiescent current to extend battery life. Consider the 23 kHz switching frequency for EMI-sensitive environments where lower noise is beneficial compared to higher frequency alternatives.

Part Context

This part belongs to the LT1173 series of micro-power DC-DC converters. It is designed as a general-purpose solution for converting voltages in portable and industrial electronics. The series is known for its simplicity and ability to function in boost, buck, or inverter modes without complex control circuitry.
