LT1173CN8-5#PBF

Overview

The LT1173CN8-5#PBF is a micro-power DC-DC converter manufactured by Analog Devices Inc. It operates in boost, buck, or inverting topologies with a fixed 5V output. The device supports an input voltage range from 2V to 30V and delivers up to 400mA of output current. Key electrical parameters include a switching frequency of 23kHz, a quiescent current of 135µA, and operation within a temperature range of 0°C to +70°C. It is housed in an 8-pin PDIP package.

Feature Summary

Versatile topology supporting step-up, step-down, and inverting configurations
Fixed output voltage options for simplified design implementation
Low quiescent current consumption suitable for battery-powered applications

Applications

Portable instrumentation power supplies
Battery-operated systems requiring voltage conversion
General-purpose DC-DC conversion circuits

Procurement Notes

Verify the specific suffix and package type against official Analog Devices documentation to ensure compatibility with your circuit requirements. Confirm RoHS compliance status and lead times through authorized distributors. Cross-reference the manufacturer part number with datasheet specifications to avoid substitution errors during procurement.

Selection Notes

Select this component when a fixed 5V output is required from varying input sources between 2V and 30V. Consider the 400mA current limit and 23kHz switching frequency for EMI constraints. Ensure the thermal performance of the PDIP package meets the application's heat dissipation needs within the specified operating temperature range.

Part Context

This part belongs to the LT1173 series of micro-power DC-DC converters. The CN8 designation indicates an 8-pin PDIP package variant. The -5#PBF suffix specifies the fixed 5V output version with lead-free packaging. This series is designed for applications requiring minimal external components and low standby power consumption.
