Kit operation
This section explains the operation, programming, and debugging modes of the kit. It also describes, in detail,
the procedure for programming and debugging the application firmware on the kit.
4.1
USB PD sink operation
The prototyping kit is designed to work as a USB PD sink. The firmware associated with the USB PD sink
functionality is available as a code example in ModusToolbox
™ software
. Firmware from that code example is
pre-loaded in the factory on these kits. CY7110, CY7111 and CY7112 kits support up to a maximum contract of
100 W (20 V, 5 A) on the EZ-
PD™
PMG1 MCU USB PD sink port. CY7113 kit supports up to a maximum contract of
140 W (28V, 5 A).

Prototyping kit in operation mode (USB PD sink-enabled firmware)
Do the following to run the USB PD sink firmware which is loaded in the factory on the CY711x EZ-P
D™
PMG1
MCU prototyping kits:
1.
Put the kit in operational mode by placing a jumper shunt on the power selection jumper (J5) at positions 1-
2 to select the USB-C power adapter as the power source for the CY711x board.
2.
Connect the USB PD sink port (J10) of the CY711x board to the USB-C power adapter using the USB Type-C
cable.
3.
Confirm that the power LED (LED4) glows green and the user LED (LED3) blinks green.
4.
Measure the DC_OUT voltage by connecting a multimeter to the terminal block (J9). Confirm that the
DC_OUT voltage value is within the 4.75 V
–
21.00 V range. The actual value is determined by the maximum
voltage which the USB-C power adapter can supply.
5.
If desired, disconnect power, remove the multimeter, connect an external load to the terminal block (J9),
and reconnect power to verify powering an external load.
Attention:
The maximum current that can be consumed by an external load is limited to 5 A by the USB
PD specification. If the load exceeds 5 A, the USB-C power adapter may trigger overcurrent
protection (OCP) and cut off the power supply to the kit. This behavior is dependent on the
implementation of the USB-C power adapter.
