Safety Information
The power adapter board must be handled with caution. The
board is directly supplied with AC supply. Most of the parts on
the board are not isolated from the AC supply. Do not touch any
part of the board when board is connected to the AC supply.
Capacitors on the board hold the charge even after
disconnecting boards from the AC supply. Handle boards using
electrical insulating material.

1. Introduction
The CCG2 18W Power Adapter (PA) Board is receptacle based Type-C power adapter. It
supports output of 5V@3Amp, [email protected], 9V@2Amps, [email protected]. The major
components on the board are Cypress’s EZ-PD CCG2 CYPD2134-24LQXIT controller and
Power Integrations’ INN2215K AC-DC controller. As shown in the photo of the PA board
below, PA board is assembly of two PCBs:
1) Main Board.
2) Daughter Board.

Introduction
The daughter board consists of CCG2 device controller, MiniProg header, reset switch SW2,
and a power switch SW1.
The CCG2 device on the board handles Type-C interface and PD 2.0 whereas AC-DC power
conversion, Over Current Protection (OCP) and Over Voltage Protection (OVP) is handled
by Power Integrations’ INN2215K AC-DC controller. It supports universal AC input supply.

Introduction
Board hardware design and BOM files are available in “Hardware and BOM” folder. CCG2
Power Adapter Firmware hex and cyacd files are available in “Firmware Binaries folder”.
The CCG2 device on the board can be programmed using PSoC Programmer and
MiniProg3 over SWD interface. Set SW1 to position 2-3 (towards MiniProg header) to turn
ON the SWD programming mode. Please refer CY4501 CCG1 Development Kit user guide
for more details on programming using the PSoC programmer. Set SW1 to position 1-2 for
normal operation.
This board also supports firmware update over USB-C and the firmware can be updated
using EZ-PD Configuration Utility. Please refer EZ-PD Configuration Utility user guide for
more details on the programming using the EZ-PD Configuration Utility.

2. Demonstration
CCG2 Power Adapter is pre-programmed and can be used with any Power Delivery Sink
devices like MacBook, Chromebook Pixel and CY4501 CCG1 host board.
Demo 1: MacBook Charging
To charge the MacBook or Type-C DRP/UFP devices, follow these steps:
1. Keep the PA board unpowered. Connect a Type-c cable to PA board and the MacBook.
Figure 2-1. PA board connected to MacBook

Demonstration
2. Plug-in power cord to the PA board. A compatible power cord is shown in the picture
below.
Figure 2-2. Power Cord
3. Plug-in power cord to AC supply. Do not touch any part of the PA board once it is
powered.
4. The PA board starts charging the MacBook. You can measure the output voltage on test
points TP2 and TP3 on the board.
5. To verify the charging power in the MacBook, Go to the Apple menu and select About
This Mac. Click on the System Report. You will see a System Information Window as
shown in figure below. In the System Information Window, click on the Power, in the
Hardware list on the left, to see power supplied by the charger.

Demo 2: Power Adapter testing using CY4501 CCG1 Host Board
All output voltage profiles of the power adapter can be demonstrated using the CCG1 host
board. The CCG1 host board is part of CY4501 Kit. More details on the Kit are available here
http://www.cypress.com/CY4501
Figure 2-4. PA board connected to CCG1 host board
To run the demo, follow the steps below:
1. Program CCG1_Power_Adapter_Tester.hex file to the CCG1 host board. The hex file is
available in “Firmware Binaries” folder. Refer CY4501 Kit guide for more details on CCG1
host board programming.
2. Setup the jumpers on the host board correctly.
a. Make sure that J4 is connected to Pin 2 and 3.
b. Keep J6 open.
The Host board gets power from the Type-C connector. No need to connect any other
external power source to the Host board.
3. Keep the PA board unpowered. Connect a Type-C cable to the PA board and CCG1 Host
board.
4. Plug a power cord to PA board. A compatible power cord is shown in Figure 2-2.
5. LED1 (Green) on the host board will turn ON.
6.
Press debug switch SW1 on the host board to change output voltage of the power
adapter. You can measure the PA output voltage on J1 connector block (Blue). External
electric load can also be connected to the J1 connector.
