Follow these general guidelines when designing the power supply:

1. 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.
2. 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.
3. 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.
4. 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.
