CY8CLEDAC02

Overview

The CY8CLEDAC02 is a high-performance offline AC-DC controller designed for dimmable LED lighting applications. It integrates a power factor correction (PFC) stage and a constant current buck converter to drive LED strings directly from the mains supply. The device features an integrated 600V MOSFET and supports direct interfacing with conventional phase-cut wall dimmers, including leading-edge and trailing-edge types, ensuring compatibility with existing infrastructure.

Feature Summary

• Integrated PFC and buck converter stages for efficient single-stage LED driving
• Direct compatibility with standard leading-edge and trailing-edge phase-cut dimmers
• Built-in 600V MOSFET reduces component count and board space
• Programmable control architecture for flexible LED string configurations

Applications

• Dimmable residential and commercial LED downlights
• LED bulbs compatible with phase-cut wall switches
• High-power LED drivers requiring power factor correction
• Offline AC-DC conversion for solid-state lighting fixtures

Procurement Notes

Verify the specific package variant and ordering suffix against Infineon's official documentation, as suffixes may indicate tape-and-reel quantities or temperature grades. Confirm end-of-life status with the manufacturer, as distribution channels may list obsolete stock. Ensure the design accounts for the integrated MOSFET thermal requirements and EMI constraints associated with offline switching topologies.

Selection Notes

Select this component for designs requiring integrated PFC and dimming without external discrete switches. It is suitable for applications needing direct wall-dimmer interaction. Evaluate thermal management needs due to the integrated power switch. Compare against separate PFC and LED driver solutions if higher efficiency or lower bill-of-materials complexity is required for non-dimmable applications.

Part Context

The CY8CLEDAC02 belongs to Infineon's family of offline LED controllers, previously developed under Cypress Semiconductor before acquisition. It addresses the market demand for smart, dimmable lighting that maintains compatibility with legacy electrical infrastructure. The device simplifies design by combining multiple functional blocks into a single IC.

Replacement Considerations

Check Infineon's official substitution guide for pin-compatible or functionally equivalent alternatives. Consider newer generations of offline LED drivers if the CY8CLEDAC02 is discontinued. Verify that any replacement maintains support for both leading-edge and trailing-edge dimming protocols.
