• Supports linear regulation with PWM dimming control
• Integrated Adaptive SourcePower technology
• Designed for high-power LED string configurations

Applications

• LED backlighting systems
• High-power white LED drivers
• RGB LED lighting solutions

Procurement Notes

Verify the specific suffix (e.g., -R) against your bill of materials, as it may indicate packaging variations. Confirm availability status, as some listings indicate limited supply or end-of-life notifications. Ensure the 44-VFQFN package type matches your PCB footprint requirements before ordering.

Selection Notes

Select this component for applications requiring precise current regulation for high-power LEDs. Consider the thermal performance of the exposed pad VFQFN package for heat dissipation. Verify that the input voltage range aligns with your system's power supply rails and that PWM dimming frequency compatibility exists with your controller.

Part Context

This part belongs to Microchip's Adaptive SourcePower series, focusing on efficient power management for lighting. It integrates control logic and power stages into a single compact solution, reducing external component count compared to discrete designs.

Replacement Considerations

Check for official replacement notices from Microchip due to potential end-of-life status. Evaluate pin-compatible alternatives if the exact package is unavailable, ensuring electrical parameters such as current rating and operating voltage remain consistent.
