Procurement Notes
Verify the NRND (Not Recommended for New Designs) status before procurement, as MPS recommends MP4026 or MP4027 for new designs. Confirm the specific suffix 'P' corresponds to reel packaging if required by your assembly line. Ensure compatibility with the 8-SOIC footprint and check moisture sensitivity level 2 requirements for storage and handling procedures.
Selection Notes
Select this component only for existing designs requiring the specific MP4021 architecture. Consider the MP4026 or MP4027 series for new projects due to the NRND status. Evaluate the 1 A output limit and 23 V max voltage against load requirements. Verify that the lack of dimming functionality aligns with system control needs.
Part Context
The MP4021GS-A-P belongs to the MP4021 family of LED drivers from Monolithic Power Systems. It is part of a broader portfolio of PMIC solutions focused on lighting applications. The GS-A variant specifically denotes the SOIC-8 package and lead-free composition. This part represents an established solution for simple, non-dimmable LED drive topologies.
Replacement Considerations
MPS explicitly recommends MP4026 and MP4027 as alternatives for new designs. These parts may offer updated features or availability compared to the NRND MP4021 series. Verify pinout and electrical parameter compatibility before substitution.
