LT1109CN8-5#PBF

Overview

The LT1109CN8-5#PBF is a step-up DC/DC converter manufactured by Analog Devices Inc. in an 8-pin PDIP package. It operates with an input voltage range of 3V to 5V and provides fixed output voltages of 5V or 12V. The device supports an output current of 30mA and utilizes a boost topology. Designed for minimal external component count, it requires only three components to function as a complete converter.

Feature Summary

Simple step-up DC/DC conversion architecture
Minimal external component requirement
Fixed output voltage options

Applications

Flash memory VPP generator circuits
Battery-powered systems requiring voltage boosting
Portable electronic devices

Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and tube packaging when sourcing. Confirm the CN8 designation corresponds to the PDIP-8 package variant. Ensure the -5# suffix matches the required fixed output voltage specification for the target application design.

Selection Notes

Select this component for applications requiring a simple boost converter with low part count. It is suitable for generating higher voltages from single-cell batteries. Consider the limited output current capability when designing power stages. Verify thermal performance within the specified operating temperature range.

Part Context

This part belongs to the LT1109 series of switching regulators. It is designed for cost-sensitive and space-constrained applications where simplicity is prioritized over high efficiency or high current delivery. The series offers fixed output variants for standard logic and memory supply levels.
