LT1109CZ-12#PBF

Overview

The LT1109CZ-12#PBF is a micropower step-up DC/DC converter manufactured by Analog Devices Inc. It operates within an input voltage range of 2 V to 9 V and provides a fixed 12 V output with a maximum current capability of 1 A. The device utilizes a boost topology and functions at a switching frequency of 120 kHz, drawing a typical quiescent current of 360 uA. Designed for surface-mount installation, it is housed in an SOIC-8 package and supports operation across a temperature range of 0°C to +70°C.

Feature Summary

Micropower efficiency suitable for battery-powered applications
Integrated shutdown control for power management
Minimal external component requirement for implementation

Applications

Flash memory VPP generation
Microprocessor DC/DC conversion
Adjustable and fixed voltage regulation

Procurement Notes

Verify the specific suffix configuration against official documentation to ensure compatibility with required pinout and electrical characteristics. Confirm availability status as supply constraints may affect lead times. Ensure the selected variant matches the intended thermal and packaging requirements for the target assembly process.

Selection Notes

Select this component when a fixed 12 V output is required from a low-voltage source up to 9 V. Consider the SOIC-8 package for surface-mount designs requiring moderate current handling. Evaluate the 120 kHz switching frequency against electromagnetic interference constraints and inductor size requirements for the specific application layout.

Part Context

This part belongs to the LT1109A series of micropower switching regulators. It is designed to replace linear regulators in low-power applications where efficiency and battery life are critical. The series offers both adjustable and fixed voltage options, providing flexibility for various portable electronic designs requiring stable power supplies.
