Overview
The CS1612-FSZ is an LED lighting driver IC from Cirrus Logic, designed for high-efficiency, cost-effective, and flicker-free solid-state lighting applications. It utilizes a flyback topology with a single-stage architecture and operates at a switching frequency of 200 kHz. The device supports Triac dimming functionality and accepts an input voltage of 17 V. It features a maximum power dissipation of 400 mW and a maximum supply current of 4.5 mA. The component is housed in a 16-SOIC package (3.90 mm wide) and is rated for operation within a temperature range of -40°C to +125°C.
Feature Summary
- Supports Triac dimming for phase-dimmable solid-state lighting applications
- Engineered to deliver high-efficiency and flicker-free performance
- Integrates digital control for cost-effective LED driver designs
Applications
- Solid-state lighting systems requiring phase dimming
- High-efficiency LED driver circuits
- Flicker-free lighting applications
Procurement Notes
Verify the End-of-Life (EOL) status prior to procurement, as the component may be discontinued or subject to limited availability. Confirm that the 16-SOIC package dimensions align with the target PCB layout. Ensure the design accommodates the specified thermal constraints given the 400 mW power dissipation rating. Validate compatibility with the required 17 V input voltage and 200 kHz operating frequency for the intended application.
Selection Notes
Select this component for applications requiring integrated digital control and Triac dimming capabilities in a compact SOIC-16 package. Consider the -40°C to +125°C operating temperature range for environmental suitability. Evaluate the 400 mW power dissipation limit against the thermal management strategy of the final product. The single-stage flyback topology offers a simplified design approach for specific LED driver implementations.
Part Context
The CS1612 belongs to the CS1610/11/12/13 series of digital control ICs developed by Cirrus Logic. These components are engineered specifically for LED lighting drivers, focusing on efficiency and flicker reduction. The manufacturer is recognized for analog and mixed-signal signal processing solutions, including audio and power management products.
Replacement Considerations
Consult official documentation for confirmed substitute part numbers. Verify pinout and electrical parameter compatibility before considering alternative components.
