CL8801K63-G

Overview

The CL8801K63-G is a sequential linear LED driver designed to drive long strings of low-current LEDs directly from AC mains. It operates with an input voltage range of 90V to 275V and provides four output channels. The device supports output currents up to 200mA and handles output voltages between 70V and 350V. Packaged in a 33-pin QFN (6x6mm) with exposed pad, it integrates offline switching and dimming capabilities without requiring external capacitors, EMI filters, or power factor correction circuits.

Feature Summary

• Eliminates the need for external capacitors, EMI filters, and power factor correction circuits typically required in LED drivers
• Enables direct connection of long LED strings to AC mains supply
• Integrates offline switching and dimming functionality within a compact package

Applications

• Direct AC mains driven LED lighting fixtures
• Long string low-current LED arrays
• Offline LED driver implementations requiring simplified bill of materials

Procurement Notes

Verify the specific suffix G and K63 against the manufacturer's current datasheet to confirm pinout and electrical specifications match your design requirements. Ensure the 33-QFN package dimensions align with your PCB footprint. Confirm that the 90-275V input range suits your local mains voltage standards. Check for any updated ordering information or alternative suffixes available from authorized distributors.

Selection Notes

Select this component when designing LED drivers that require elimination of bulky passive components like capacitors and EMI filters. It is suitable for applications needing direct AC mains operation with multiple output channels. Consider the 33-QFN package size for space-constrained designs. Verify thermal management requirements for the exposed pad configuration under maximum load conditions.

Part Context

The CL8801K63-G belongs to Microchip's CL8800/CL8801 family of sequential linear LED drivers. These devices are engineered for cost-effective, high-reliability LED lighting solutions by simplifying the circuit topology. The K63 suffix denotes the specific package variant and tape-and-reel packaging option, distinguishing it from other package styles within the same functional family.

Replacement Considerations

Consult Microchip Technology documentation for verified cross-reference part numbers. Ensure any substitute maintains the 4-channel architecture, 33-QFN package, and compatible input/output voltage ranges. Verify that replacement parts offer equivalent dimming capabilities and thermal performance characteristics.
