LS9100X-S

Overview

The LS9100X-S is an AC/DC offline LED driver IC designed for direct high-voltage AC input applications. It integrates a full-bridge rectifier, current limiter source circuit, and protection mechanisms into a single package. The device supports triac dimming functionality and delivers a regulated output current of 50mA to a single LED channel. Housed in an 8-SOP-EP package, it offers a compact solution for lighting controls requiring flicker-free operation and high power factor without external complex components.

Feature Summary

• Integrates high-voltage full-bridge rectifier with current limiting and protection circuits
• Supports triac dimming for compatibility with standard wall switch products
• Provides flicker-free LED drive capability for stable illumination

Applications

• Direct AC LED lighting fixtures
• Wall switch integrated lighting products
• Dim-to-warm evaluation boards and systems
• High voltage LED direct AC drivers

Procurement Notes

Verify the specific suffix 'S' against the manufacturer's latest datasheet to confirm pinout and thermal pad configuration. Ensure the component meets ISO 9001:2000 quality standards as certified by LSI/CSI. Cross-reference the part number with authorized distributors to avoid counterfeit units, as the manufacturer maintains strict quality control through dedicated inspection centers.

Selection Notes

Select this IC for designs requiring direct connection to mains AC voltage without bulky transformers. It is suitable for low-power LED engines needing precise 50mA current regulation. Consider the 8-SOP-EP package for thermal management needs. Verify that the application environment supports the integrated protection features and triac dimming requirements specified in the official documentation.

Part Context

LSI/CSI is a fabless semiconductor company established in 1969, specializing in custom and standard integrated circuits. The company holds ISO 9001:2000 certification since 1996. The LS9100X belongs to their series of dimmable, flicker-free LED light stick and direct AC driver solutions, targeting lighting controls and consumer electronics markets.

Replacement Considerations

Consult the official LSI/CSI resources for confirmed substitute part numbers. No public cross-reference data is available for generic replacements. Ensure any alternative component matches the 8-SOP-EP package and 50mA output specification.
