Procurement Notes
Verify the exact part number and manufacturer details before procurement, as this component is listed as discontinued. Confirm availability through authorized distributors or secondary market suppliers. Ensure compatibility with existing system designs given the obsolete status. Check for any specific handling requirements associated with legacy Microsemi components.
Selection Notes
Select this component only if discontinuous conduction mode operation at 1.7MHz meets design requirements. Consider the 8-DIP package constraints for PCB layout. Evaluate alternative modern PFC controllers if current production is required, due to the discontinued status. Verify voltage ratings and pin configurations against the original schematic specifications.
Part Context
This component belongs to the Microsemi power management IC category, specifically within the power factor correction segment. It represents legacy technology from the Microsemi Corporation product line, now part of Microchip Technology. The device serves specialized roles in older power supply architectures where DCM efficiency was prioritized.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Due to the discontinued status, engineers should consult Microchip's official obsolescence notices for recommended upgrades or equivalent modern alternatives that support similar discontinuous mode operations.
