LT1173CS8#TRPBF

Overview

The LT1173CS8#TRPBF is a versatile micro-power DC-DC converter manufactured by Analog Devices Inc. It supports boost, buck, and inverting topologies within an 8-pin SOIC package. The device operates with an input voltage range of 2V to 30V and delivers up to 800mA output current. Key electrical parameters include a switching frequency of 23kHz, a quiescent current of 110uA, and an operating temperature range from 0°C to +70°C. This component functions as a single-output adjustable or fixed voltage regulator suitable for low-power applications.

Feature Summary

• Supports multiple conversion modes including step-up, step-down, and inverting configurations
• Operates effectively with minimal external components for fixed output voltages
• Designed for micro-power applications with low static current consumption

Applications

• Battery-powered portable devices requiring efficient voltage regulation
• Systems needing both step-up and step-down conversion capabilities
• Inverting power supply circuits for analog signal processing

Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging distinct from tube variants. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the SOIC-8 package dimensions match your PCB footprint requirements. Cross-reference the datasheet revision date to validate parameter accuracy against your design specifications.

Selection Notes

Select this component when designing circuits that require flexible topology options such as boosting low battery voltages or bucking higher sources. Consider the 800mA current limit and 23kHz switching frequency for EMI-sensitive designs. Evaluate the 110uA quiescent current impact on standby power budgets. Compare against fixed-voltage variants if specific output levels like 5V or 12V are required without external adjustment resistors.

Part Context

This part belongs to the LT1173 series of micro-power DC-DC converters from Analog Devices. It shares functional similarities with other members like the LT1173CN8 but differs in package type and reel configuration. The series is characterized by its ability to perform multiple conversion types using a minimal component count, making it a staple for compact power management solutions in consumer electronics.

Replacement Considerations

LT1173CS8#PBF is a compatible alternative differing primarily in packaging format.
