Procurement Notes
Verify component status as this specific part number is listed as obsolete by the manufacturer. Confirm availability through authorized distributors or secondary markets if production continuity is required. Ensure datasheet revisions match the specific batch requirements for legacy projects.
Selection Notes
Select this component for applications requiring integrated high-voltage startup and flyback control. Consider the 650V breakdown rating for appropriate voltage headroom. Evaluate the 8-DIP package constraints against PCB layout requirements. Verify compatibility with the target switching frequency range of 10kHz to 200kHz.
Part Context
This component belongs to NXP's STARplug family, designed for cost-effective offline power solutions. It combines power switching and control functions into a single package to reduce external component count. The series targets standard isolated power supply applications requiring reliable performance.
Replacement Considerations
As the part is obsolete, identify equivalent flyback controllers with similar 650V ratings and DIP-8 packaging. Verify pin compatibility and electrical specifications before substitution. Consult official replacement guides for discontinued NXP power management ICs.
