LT1111CJ8-12

Overview

The LT1111CJ8-12 is a micropower DC/DC converter manufactured by Analog Devices Inc. It operates with an input voltage range of 2V to 30V and provides a fixed 12V output at up to 800mA. The device supports both buck and boost topologies within a single package. Key electrical parameters include a switching frequency of 72kHz and a quiescent current of 300uA. It is housed in an 8-pin CDIP package and functions within a temperature range of 0°C to +70°C.

Feature Summary

Supports both step-down (buck) and step-up (boost) conversion topologies
Operates from low input voltages starting at 2V
Delivers fixed 12V output with high efficiency for micropower applications

Applications

Battery-powered portable electronics requiring voltage regulation
Systems needing isolation between positive and negative supply rails
Micropower data acquisition systems
Industrial control circuits with varying input sources

Procurement Notes

Verify the specific suffix 'CJ8' indicates a ceramic DIP package variant distinct from SOIC versions. Confirm RoHS compliance status as some legacy listings may vary. Check manufacturer archives for active production status or obsolescence notices before finalizing procurement plans.

Selection Notes

Select this component when a fixed 12V output is required from a wide input range. Ensure the application does not require shutdown functionality, as this model lacks it. Consider thermal management for the ceramic package if operating near maximum current limits.

Part Context

This part belongs to the LT1111 series of micropower DC/DC converters. It shares functional similarities with other variants like LT1111IS8 but differs in package type and output configuration. The series is known for minimal external component requirements.
