LS9200

Overview

The LS9200 is a monolithic CMOS device designed for driving and dimming LED networks. It functions as a system-level LED dimmable driver IC, providing regulated constant current output. The device supports AC/DC offline switching applications with step-up (boost) topology. It features PWM dimming capability and delivers up to 200mA of output current. The component is housed in an 8-SOP-EP package.

Feature Summary

• Monolithic CMOS construction for integrated LED network driving and dimming
• Regulated constant current output maintained via external sense resistor
• Supports PWM dimming for seamless LED network control
• Designed for AC/DC offline switcher step-up applications

Applications

• LED network driving systems
• Dimmable LED lighting controls
• AC/DC offline power supply circuits
• Step-up converter applications for LED loads

Procurement Notes

Verify the manufacturer designation carefully, as LSI/CSI refers to distinct entities from LSI Logic. Confirm the specific package type and pinout against the official datasheet to ensure compatibility with your PCB layout. Check for RoHS compliance status if required by your manufacturing standards. Ensure the source document explicitly identifies this part as an LED driver to avoid confusion with other LSI-branded components.

Selection Notes

Select this component when a monolithic solution for LED dimming and driving is required. It is suitable for designs needing regulated constant current without complex external circuitry. Consider the 200mA output limit and 8-SOP-EP package constraints during thermal and space planning. Verify that the application voltage range matches the boost converter capabilities specified in the technical documentation.

Part Context

The LS9200 belongs to the family of LED driver integrated circuits offered by LSI/CSI. It is distinct from the SAS host bus adapters produced by LSI Logic Corporation. This component focuses on power management and lighting control rather than data storage interfaces. It represents a specialized solution for analog LED control within mixed-signal environments.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Consult the manufacturer's obsolescence notices or equivalent function guides for potential alternatives. Ensure any replacement maintains the same constant current regulation and PWM dimming interface requirements.
