LT1111CN8#PBF

Overview

The LT1111CN8#PBF is a micropower DC/DC converter manufactured by Analog Devices Inc. It operates with an input voltage range of 2 V to 30 V and provides a fixed 5 V output at up to 800 mA. The device utilizes a PDIP-8 through-hole package and supports both boost and buck topologies. It features a switching frequency of 72 kHz and a quiescent current of 300 uA. The component functions within a temperature range of 0°C to +70°C.

Feature Summary

Supports adjustable and fixed output voltages including 5V and 12V configurations
Capable of step-up (boost) and step-down (buck) conversion topologies
Designed for micropower applications with low static current consumption

Applications

Battery-powered portable equipment requiring efficient voltage regulation
Systems needing isolation between input sources and regulated loads
Circuits utilizing single-cell alkaline or nickel-cadmium batteries

Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and RoHS status before procurement. Confirm the PDIP-8 through-hole package availability as surface-mount variants exist. Check manufacturer lifecycle status, as this part may be discontinued or subject to limited supply constraints in certain regions.

Selection Notes

Select this component when a through-hole solution is required for buck-boost applications. Ensure the 800 mA output current meets load requirements. Verify that the 72 kHz switching frequency aligns with electromagnetic interference constraints. Consider the 300 uA quiescent current impact on overall system battery life.

Part Context

This part belongs to the LT1111 series of micropower DC/DC converters from Analog Devices. The CN8 designation specifies the commercial temperature grade and PDIP-8 package. The #PBF suffix denotes lead-free packaging compliant with environmental directives. It serves as a versatile power management IC for low-power systems.
