CL8801K63-G-M935

Overview

The CL8801K63-G-M935 is a four-channel LED driver IC manufactured by Microchip Technology. It utilizes a Buck topology to regulate current for high-power LED applications. The device is housed in a QFN-33-EP package with dimensions of 6x6 mm, featuring an exposed pad for thermal management. It supports a minimum input voltage of 90V and a maximum input voltage of 33V, indicating specific operational constraints within its circuit design.

Feature Summary

• Four independent output channels for precise LED current control
• Buck converter topology for efficient power regulation
• Thermal enhanced QFN package for improved heat dissipation

Applications

• High-power LED lighting systems
• Industrial LED illumination
• Commercial lighting fixtures

Procurement Notes

Verify the component authenticity through authorized Microchip distributors or certified suppliers. Confirm the package marking matches the CL8801K63-G-M935 designation. Ensure the supply chain documentation includes RoHS compliance certificates as indicated in available product listings. Check for any specific handling requirements related to the exposed pad thermal structure during assembly.

Selection Notes

Select this component when designing circuits requiring four-channel LED drive capability with a Buck topology. Consider the 6x6 mm QFN package size for space-constrained PCB layouts. Evaluate the input voltage range compatibility with the system power supply. Ensure thermal design accounts for the exposed pad requirement to maintain reliable operation under load.

Part Context

This part belongs to the CL8801 series of LED drivers from Microchip Technology, originally developed under the Supertex brand before acquisition. The series focuses on high-efficiency LED regulation. The specific suffix indicates packaging and tape-and-reel configuration details consistent with Microchip's standard ordering nomenclature for surface-mount devices.

Replacement Considerations

Direct substitutes include other parts within the CL8801 family such as CL8801K63-G. Verify pinout compatibility and electrical specifications before substitution. Cross-reference with similar four-channel Buck LED drivers if exact matches are unavailable.
