Procurement Notes
Verify component authenticity through authorized Microchip Technology distributors. Confirm the specific suffix 'INR' corresponds to the tape and reel packaging format. Check for end-of-life status or obsolescence notices, as this part may be discontinued. Ensure compatibility with existing PCB footprints for the 24-VQFN package before procurement.
Selection Notes
Select this component for designs requiring integrated AC-DC conversion and dual-channel LED driving. Consider the 24-VQFN package size for space-constrained applications. Evaluate thermal performance within the specified operating temperature range. Verify that the PWM dimming interface matches the control system requirements.
Part Context
This component belongs to the MSL2023/MSL2024 series from Microchip Technology. These devices are engineered for high Color Rendering Index (CRI) LED luminaires. The series emphasizes adaptive headroom control and individual PWM dimming capabilities for enhanced lighting quality.
Replacement Considerations
Publicly confirmed parameter-equivalent substitutes include MSL2021-IN and MSL2024-IN from Microchip Technology. Verify pinout and electrical specifications against the original datasheet when transitioning to these alternatives.
