1.3 Considerations

  • This PFC needs to be used together with the C2000 control card TMDSCNCD28P55X and PMP20306 isolated bias supply reference design.
  • Due to the totem-pole topology, the PFC ground (PGND) is floating. This can lead to common-mode current issues with improper test equipment setups. Always use isolated differential voltage probes when measuring voltage signals.
