Overview
The CS1616-FSZ is an integrated LED driver IC designed for offline AC/DC applications. 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 adjustable from 6kHz to 200kHz. Packaged in a 16-SOIC format, it functions reliably across a temperature range of -40°C to +125°C TJ.
Feature Summary
- Supports multiple power conversion topologies including Flyback, Step-Down (Buck), and Step-Up (Boost) configurations.
- Enables seamless integration with Triac-based dimming systems for lighting control.
- Operates as an AC/DC offline switcher without requiring internal power switches.
Applications
- LED lamp drivers
- Offline AC/DC power supplies
- Dimmable lighting fixtures
Procurement Notes
This component is officially listed as End of Life (EOL). Availability is restricted or non-existent through standard distribution channels. Verify current stock status and lead times with authorized suppliers before design finalization. Consider obsolescence management strategies due to discontinued manufacturing status.
Selection Notes
Select this IC for designs requiring flexible topology support (Flyback/Buck/Boost) and Triac dimming compatibility. Ensure the application environment stays within the specified -40°C to +125°C junction temperature range. Confirm that the input voltage requirements align with the 11V to 17V operating window for stable performance.
Part Context
Part of the Cirrus Logic CS161x series, which includes variants like CS1615 and CS1616. These components are specialized single-stage controllers for LED lighting applications. The CS1616 variant specifically distinguishes itself by supporting additional buck and boost capabilities alongside flyback operation.
Replacement Considerations
Public confirmed substitute part numbers: CS1615-FSZR, CS1616-FSZR, CS1616-FZZR. Verify pinout and electrical parameter compatibility when substituting these specific variants.
