LT1108CN8#PBF

Overview

The LT1108CN8#PBF is a micropower DC/DC converter manufactured by Analog Devices Inc. It operates in buck, boost, or inverting topologies with an input voltage range of 2V to 30V. The device provides fixed output voltages of 5V or 12V and supports an output current of up to 0.15A. Designed for minimal external component count, it requires only four components to function. The unit is housed in an 8-pin DIP package.

Feature Summary

• Versatile topology supporting step-up, step-down, and inverting configurations
• Micropower design requiring only four external components
• Fixed output options available at 5V and 12V

Applications

• Palmtop computer logic power supplies
• Battery-powered systems requiring voltage inversion
• Low-power portable electronics

Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm pinout and electrical characteristics. Confirm RoHS compliance status through the manufacturer's datasheet. Check authorized distributor availability as supply may be limited. Ensure the package type matches the required PCB footprint before ordering.

Selection Notes

Select this component when a simple, low-cost solution for converting battery voltages to standard logic levels is required. It is suitable for applications where board space is constrained due to the minimal external component requirement. Consider the fixed output voltages when designing circuits that do not require adjustable regulation.

Part Context

This part belongs to the LT1108 family of micropower DC/DC converters. The CN8 suffix indicates an 8-pin DIP package variant. Other variants in the series include CS8 (SOIC) and different output voltage codes such as -5 and -12. The family is characterized by its ability to operate from a single supply source across various conversion modes.

Replacement Considerations

LT1108CS8-5: Same functionality in SOIC-8 package. LT1108CN8-12: Same package with 12V fixed output.
