Procurement Notes
Verify the complete part number including suffixes against official onsemi documentation to ensure correct package and temperature grade. Confirm RoHS compliance status through the specific datasheet revision. Cross-reference ordering information with authorized distributors to validate availability and authenticity before procurement.
Selection Notes
Select this component when a dual-channel solution with combined buck-boost capability is required for low-voltage LED applications. Ensure the design accommodates the 40 mA output limit and the specific SC-70-6 footprint constraints. Validate that the system power supply remains within the 2.4 V to 5.5 V operating range for reliable performance.
Part Context
This device belongs to the CAT4002A series of LED drivers from onsemi. The series focuses on providing efficient current regulation for small-scale LED arrays. The ASD suffix typically denotes specific packaging and environmental characteristics consistent with onsemi's standard product coding conventions for surface-mount devices.
Replacement Considerations
Consult onsemi technical support or official cross-reference lists for verified substitutes. Generic equivalents may not match the specific buck-boost topology or dimming interface requirements.
