Figure 4-1. CY6611 EVK Hardware Interfaces
Note
: The maximum power consumed by all ports should not exceed 55 W when used with the power adapter provided with
the kit. If the total power requirement for the devices to be connected to the ports of CY6611 EVK exceeds 55 W, use a higher
capacity power source to power the kit. The new power source can be a higher capacity power adapter or bench power
supply. The power adapter needs to be connected to the kit through the DC Power Jack (J12) and the bench power supply
need to be connected on the DC Terminal (J11).
Following is the criteria for the Power Adapter if new Power Adapter with higher capacity is required:
Maximum output voltage of 20 V
DC Barrel specification:
Polarity: Center Positive
Outer diameter: 5.5 mm
Inner diameter: 2.1 mm
Safety approvals such as UL
Note
: Check and ensure that the power adapter has the necessary safety approvals required for the country where it is
used
Important Notes
Do not supply power to the CY6611 kit hardware at both the power interfaces (J12 and J11). Doing so may damage the
kit hardware.
Make sure that bench power supply is connected to the kit hardware (J11) as per the marked polarity. Also, ensure that
the maximum output from the bench power supply does not exceed 20 V.
Make sure t
hat the DC plug of the power adapter is of ‘Center Positive’ type. Using a power adapter with incorrect polarity
may permanently damage the kit hardware.
