Overview
The CS1610-FSZ is a digital control IC designed for high-efficiency, cost-effective, flicker-free, phase-dimmable solid-state lighting applications. It utilizes a flyback topology with an operating frequency of 200 kHz and supports Triac dimming. The device operates within a supply voltage range of 17 V and functions across a temperature range of -40°C to +125°C. Packaged in a 16-SOIC format, it features a maximum power dissipation of 400 mW and a maximum supply current of 4.5 mA.
Feature Summary
- Digital control architecture for efficient LED driver implementation
- Supports phase-dimming functionality compatible with Triac controls
- Designed to deliver flicker-free performance in solid-state lighting
Applications
- Phase-dimmable LED lighting systems
- Solid-state lighting drivers
- Flyback converter based LED illumination
Procurement Notes
This component is officially classified as End of Life (EOL) by Cirrus Logic Inc. and is no longer manufactured. Availability is restricted to existing stock or obsolete channels. Verify part authenticity carefully when sourcing from third-party distributors, as new production units are not available. Ensure compatibility with replacement components before procurement.
Selection Notes
Select this component only if legacy design compatibility is required, as it is discontinued. Consider the 16-SOIC package constraints and 200 kHz switching frequency during layout. Evaluate thermal management for the 400 mW power dissipation limit. Review official substitution lists for active alternatives that maintain similar electrical characteristics and pinout configurations.
Part Context
The CS1610 belongs to a series of digital control ICs engineered for solid-state lighting. It represents Cirrus Logic's approach to integrating efficiency and dimming capabilities into a single chip. The FSZ suffix indicates specific packaging and handling specifications within the product line. This model serves as a foundational solution for non-isolated LED driver topologies requiring precise digital control.
Replacement Considerations
Official substitutes include the CS1610-FSZR and related variants within the CS161x family. Verify pinout compatibility and thermal requirements when transitioning to active replacements. Consult manufacturer documentation for direct cross-reference data.
