LT1111CS8-12#PBF

Overview

The LT1111CS8-12#PBF is a micropower DC/DC converter manufactured by Analog Devices Inc. It operates within an input voltage range of 2 V to 30 V and delivers a fixed output voltage of 12 V at up to 800 mA. The device supports both boost and buck topologies with a switching frequency of 72 kHz. It features a low quiescent current of 300 uA and functions reliably across an operating temperature range of 0°C to +70°C. Packaged in an 8-SOIC surface-mount format, it serves as a compact power management solution for battery-powered applications.

Feature Summary

Supports both step-up (boost) and step-down (buck) voltage conversion topologies
Designed for micropower applications with low static current consumption
Provides a fixed 12 V output configuration

Applications

Battery-powered microprocessor systems
Portable instrumentation requiring stable 12 V rails
Industrial control circuits with varying input sources

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified suppliers. Confirm the specific suffix matches the required fixed 12 V output variant. Check RoHS compliance status and manufacturing date codes against project requirements. Ensure storage conditions prevent moisture damage prior to soldering.

Selection Notes

Select this part when a fixed 12 V output is required from a wide input range between 2 V and 30 V. Consider the 800 mA load capability and 72 kHz switching frequency for filter component sizing. Evaluate the SOIC-8 package constraints for thermal management and PCB layout space compared to adjustable variants in the LT1111 family.

Part Context

This component belongs to the LT1111 series of micropower DC/DC converters. It shares the core architecture with other variants like the LT1111CS8#PBF but differs in its fixed output voltage specification. The series is known for high efficiency in low-power portable electronics and industrial sensors.
