Follow these general guidelines when
designing the power supply:
- The port-side supply, VDD1, should be 3.3-V (typical) and should meet
the recommended operating conditions outlined in Section 6.3 in terms of DC voltage, AC noise, and start-up ramp time. If using
the FPC202 to control a power switch to enable/disable power to the front-port
connectors, the FPC202 should be connected to 3.3-V power on the input side of
the switch.
- The host-side supply, VDD2, should be 1.8-V to 3.3-V (typical) and
should meet the recommended operating conditions outlined in Section 6.3 in terms of DC voltage, AC noise, and start-up ramp time.
- The maximum current draw for the FPC202 is provided in Section 6.5. This figure can be used to calculate the maximum current the supply
must provide.
- The FPC202 does not require any special power supply filtering (that
is, ferrite bead), provided the recommended operating conditions are met. Only
standard de-coupling is required. Refer to Section 5 for details concerning the recommended supply decoupling for each pin.
