- General illumination systems
Procurement Notes
Verify the specific suffix 'MR2G' against the manufacturer's official datasheet to confirm pinout compatibility and packaging specifications. Ensure that the design requirements align with the 35V supply and 65 kHz frequency limits documented for this component. Cross-reference the RoHS status and environmental compliance data directly from onsemi documentation before procurement.
Selection Notes
Select this component for designs requiring primary-side regulation without optocouplers. The integrated thermal foldback feature simplifies thermal management in enclosed LED fixtures. Verify that the input voltage range and output power requirements fall within the capabilities defined in the official electrical characteristics table.
Part Context
This part belongs to the NCL300xx series of LED driver controllers from onsemi. These devices are engineered for cost-effective and high-performance lighting solutions. The series emphasizes simplified bill of materials by eliminating the need for secondary side feedback components while maintaining accurate current regulation.
Replacement Considerations
Consult onsemi official substitution guides for direct replacements. Verify pin-to-pin compatibility and electrical parameter equivalence with any alternative part numbers before implementation.
