Procurement Notes
Verify current availability status as the component is listed as obsolete or end-of-life by the manufacturer. Confirm compatibility with existing design specifications before procurement planning. Check for alternative sources or last-time buy options through authorized distributors. Ensure compliance with RoHS directives and material composition declarations required for final product certification.
Selection Notes
Select this component only if the application requires an integrated solution for PoE PD power conversion. Consider the TSSOP-20 package constraints for PCB layout. Evaluate thermal performance requirements given the 13W power handling capability. Verify that the control mode and frequency characteristics align with the system's electromagnetic interference limits.
