CS1612-FSZR

Overview

The CS1612-FSZR is an AC/DC offline switcher LED driver IC from Cirrus Logic, housed in a 16-SOIC package. It supports Flyback, Buck, and Boost topologies with Triac dimming capability. The device operates within a supply voltage range of 11V to 17V and features a switching frequency up to 200 kHz. It functions reliably across a temperature range of -40°C to +125°C TJ, with a maximum power dissipation of 400 mW.

Feature Summary

• Supports multiple converter topologies including Flyback, Buck, and Boost for versatile LED lighting designs.
• Integrates Triac dimming functionality for compatibility with standard phase-cut dimmers.
• Designed for high-temperature operation suitable for enclosed or high-stress environments.

Applications

• General LED lighting systems
• Offline AC/DC power supplies for illumination
• Triac-dimmable LED fixtures

Procurement Notes

This component is officially listed as End-of-Life (EOL) by the manufacturer. Availability is restricted, and sourcing may require checking secondary markets or authorized distributors for remaining stock. Verify RoHS compliance status through official certificates before procurement planning.

Selection Notes

Select this part for applications requiring integrated Triac dimming and multi-topology support in a compact SOIC package. Ensure input voltage requirements align with the 11V to 17V operating range. Consider thermal management due to the 400 mW power dissipation limit and surface-mount installation style.

Part Context

The CS1612 belongs to the CS16xx series of LED drivers from Cirrus Logic. It shares architectural similarities with related models like the CS1615 and CS1616, offering comparable dimming and topology features within the same 16-SOIC form factor family.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. As the device is EOL, consult official Cirrus Logic resources for current recommended replacements or equivalent functional alternatives.
