Procurement Notes

Verify the component status as obsolete or end-of-life through official manufacturer channels before procurement planning. Confirm that the specific suffix matches the required electrical characteristics, as variations may exist. Ensure compliance with RoHS standards if applicable to your region. Request updated lifecycle notifications directly from Diodes Incorporated to mitigate supply chain risks associated with discontinued products.

Selection Notes

Select this component for designs requiring a single-chip solution for high-voltage LED driving. The integrated MOSFET reduces external component count compared to discrete solutions. Verify that the 1 A current limit aligns with the target LED string requirements. Consider the thermal performance within the specified operating temperature range during PCB layout.

Part Context

This part belongs to the AL1677 series of LED drivers designed for universal AC inputs. It is distinct from other Diodes Incorporated LED controllers by its specific integration of a high-voltage MOSFET and boundary conduction mode operation. The series targets cost-sensitive and space-constrained lighting applications requiring high reliability.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. As the component is listed as obsolete, alternative sourcing should focus on verifying equivalent functional specifications from other manufacturers rather than direct cross-references.
