LT1111CN8-12#PBF

Overview

The LT1111CN8-12#PBF is a micropower DC/DC converter manufactured by Analog Devices Inc. It operates in both buck and boost topologies with a fixed 12 V output. The device supports an input voltage range from 2 V to 30 V and delivers up to 1.5 A of switch current. It features a switching frequency of 72 kHz and a quiescent current of 300 uA. The component is housed in an 8-DIP package and functions within a temperature range of 0°C to 70°C.

Feature Summary

Supports buck and boost conversion topologies for flexible power management
Fixed 12 V output configuration ensures stable voltage regulation
Micropower design with low quiescent current consumption

Applications

Battery-powered portable electronics requiring efficient voltage conversion
Systems needing step-up or step-down regulation from varying input sources
Embedded applications utilizing standard DIP packaging for through-hole assembly

Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and PDIP packaging when sourcing. Confirm availability status as distribution channels may list limited stock or end-of-life conditions. Ensure the fixed 12 V output variant matches the circuit requirements, as other output voltages exist within the same series. Cross-reference the manufacturer part number with official distributor catalogs to avoid counterfeit components.

Selection Notes

Choose this component when a fixed 12 V output is required alongside bidirectional buck-boost capability. The 1.5 A switch current rating suits moderate load applications compared to lower-current variants. The 8-DIP package facilitates easy prototyping and through-hole integration. Consider the 72 kHz switching frequency for EMI constraints and external component sizing relative to higher-frequency alternatives.

Part Context

This part belongs to the LT1111 series of micropower DC/DC converters from Analog Devices. The CN8-12 designation specifies the commercial temperature grade, 8-pin DIP package, and fixed 12 V output. It complements other variants offering different outputs or surface-mount packages within the same functional family.
