Overview
The CS1615-FSZR is a single-stage dimmable offline AC/DC controller IC designed for LED lighting applications. It utilizes a flyback topology and supports Triac dimming functionality. The device operates within a switching frequency range of 6 kHz to 200 kHz and accepts an input voltage of 17 V. It features a power dissipation rating of 400 mW and draws a maximum supply current of 4.5 mA. The component is housed in a 16-SOIC package with a width of 3.90 mm. It functions reliably across a temperature range of -40°C to +125°C TJ.
Feature Summary
- Integrates single-stage offline AC/DC conversion with built-in brightness control capabilities
- Supports Triac-based dimming protocols for compatible lighting systems
- Operates with variable frequency switching from 6 kHz to 200 kHz
Applications
- LED lamp drivers
- Dimmable lighting fixtures
- Offline AC/DC power supplies for illumination
Procurement Notes
Verify the End-of-Life (EOL) status prior to procurement, as official documentation indicates this product has been discontinued. Confirm RoHS compliance requirements against specific project standards. Ensure that the 16-SOIC package dimensions align with existing PCB footprints. Check for any Product Change Notices (PCN) related to labeling or assembly variations that may affect integration.
Selection Notes
Select this component only if single-stage flyback topology meets system efficiency targets. Verify compatibility with Triac dimmers used in the target application environment. Consider the 400 mW power dissipation limit when designing thermal management solutions. Evaluate the 17 V input specification against available line voltages to ensure stable operation under all expected conditions.
Part Context
This part belongs to the Cirrus Logic CS1615 series, which focuses on integrated LED driver solutions. The series typically includes variants like the CS1616, sharing similar architectural foundations for offline AC/DC conversion. These components are engineered to simplify LED driver design by combining control logic and power stage management into a single monolithic IC.
Replacement Considerations
Public confirmed substitute part numbers are not available due to the End-of-Life status. Designers should evaluate alternative single-stage LED driver ICs from other manufacturers that support Triac dimming and offer comparable SOIC-16 packaging.
