LT1110CS8-5#PBF

Overview

The LT1110CS8-5#PBF is a versatile micro-power DC-DC converter manufactured by Analog Devices Inc. It operates as a switching regulator capable of non-inverting, inverting, step-up, and step-down topologies. The device accepts an input voltage range from 1V to 30V and provides a fixed 5V output. Packaged in an 8-pin SOIC-N surface-mount format, it requires only three external components for operation.

Feature Summary

• Supports multiple conversion topologies including buck, boost, inverting, and SEPIC configurations
• Operates with a wide input voltage range suitable for single-cell battery applications
• Requires minimal external component count for fixed voltage regulation

Applications

• Single cell to 5V DC-DC conversion circuits
• Portable devices requiring efficient power management from low-voltage sources
• Battery-powered systems utilizing step-up or step-down regulation

Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance when sourcing. Confirm availability status as distribution channels may report limited supply. Ensure the 8-pin SOIC package matches your PCB footprint requirements before finalizing procurement orders.

Selection Notes

Select this component when a fixed 5V output is required from a variable input between 1V and 30V. It is suitable for designs prioritizing low external component count over adjustable output flexibility. Consider thermal performance within the SOIC-8 package for your specific current load requirements.

Part Context

This part belongs to the LT1110 family of micro-power DC-DC converters. It shares functional similarities with other fixed-output variants like the LT1110CS8-12#PBF but differs in its regulated output voltage specification. The CS8 designation denotes the commercial temperature range and SOIC-8 package style.

Replacement Considerations

LT1110CS8-12#PBF offers identical topology and packaging with a 12V fixed output instead of 5V.
