Overview
The CS1630-FSZR is a two-channel TRIAC dimmable LED driver IC manufactured by Cirrus Logic. It operates as an AC/DC offline switcher supporting Flyback, Buck, and Boost topologies. The device functions within a supply voltage range of 11V to 17V and supports switching frequencies from 625Hz to 200kHz. It features no internal switches and delivers an output current of 5mA per channel. The component is housed in a 16-SOIC package with a 3.90mm width and is rated for operation between -40°C and 125°C junction temperature.
Feature Summary
- Supports TRIAC dimming functionality for lighting applications
- Integrates AC/DC offline switching capabilities
- Compatible with Flyback, Buck, and Boost converter topologies
Applications
- LED lighting systems requiring TRIAC dimming
- Offline AC/DC power conversion designs
- General illumination products
Procurement Notes
Verify the specific suffix 'FSZR' against official documentation to confirm tape-and-reel packaging versus bulk options. Confirm RoHS compliance status and lead-free certification details directly with the manufacturer or authorized distributors prior to procurement. Ensure the component matches the required 16-SOIC physical dimensions and thermal specifications for the target application.
Selection Notes
Select this component for designs requiring integrated TRIAC dimming control without external discrete switching elements. Consider the 11V-17V operating range and 625Hz-200kHz frequency limits when designing the power stage. Verify that the 16-SOIC package fits the PCB layout constraints and that the -40°C to 125°C junction temperature rating meets the environmental requirements of the installation.
Part Context
The CS1630 series belongs to Cirrus Logic's portfolio of power management integrated circuits designed for LED drivers. This specific model focuses on providing efficient control for dimmable lighting solutions. It complements other components in the company's energy measurement and audio processing lines by addressing the growing demand for smart, dimmable LED infrastructure.
Replacement Considerations
Check for direct substitutes within the CS16xx family, such as the CS1616, which shares similar TRIAC dimming and topology support. Verify pinout compatibility and electrical parameter alignment before substituting. Consult official change notices for any functional differences between variants.
