LT1109CN8-12#PBF

Overview

The LT1109CN8-12#PBF is a monolithic DC/DC converter manufactured by Analog Devices Inc., designed for step-up (boost) applications. It operates within an input voltage range of 2 V to 9 V and provides a fixed output voltage of 12 V. The device supports a maximum output current of 1 A with a typical switching frequency of 120 kHz. It features a low quiescent current of 360 uA and includes shutdown functionality. The component is housed in an 8-pin SOIC package and is rated for operation between 0°C and +70°C.

Feature Summary

Integrated boost topology for efficient voltage step-up conversion
Fixed 12 V output configuration suitable for flash memory programming
Shutdown pin enables power management and extended battery life
Compact surface-mount packaging facilitates space-constrained designs

Applications

Flash memory voltage generation
Battery-powered portable devices
General-purpose DC/DC conversion
Microprocessor power supplies

Procurement Notes

Verify the specific suffix 'CN8' against official Analog Devices documentation to confirm commercial grade temperature rating and SOIC package variant. Ensure the '#PBF' designation aligns with lead-free compliance requirements. Cross-reference the part number with manufacturer datasheets to validate availability and manufacturing status before procurement.

Selection Notes

Select this component when a fixed 12 V output is required from a 2 V to 9 V input source. Consider the 1 A output current capability and 120 kHz switching frequency for efficiency needs. Evaluate the 0°C to +70°C operating range against environmental constraints. Compare static current consumption with alternative regulators if battery longevity is critical.

Part Context

The LT1109 series comprises high-efficiency step-up DC/DC converters optimized for battery-powered systems. The LT1109CN8-12#PBF represents a specific variant within this family, offering a fixed 12 V output in a standard industrial temperature range. It belongs to Analog Devices' portfolio of power management integrated circuits designed for compact, high-performance applications.
