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. CCG2 18W Power Adapter RDK User Guide, Version 0.5 4 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. Figure 1-1: CCG2 18W Power Adapter board Daughter Board Main Board CCG2 18W Power Adapter RDK User Guide, Version 0.5 5 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. Figure 1-2: Daughter Board MiniProg Header SW1 CCG2 SW2 (Reset) CCG2 18W Power Adapter RDK User Guide, Version 0.5 6 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. CCG2 18W Power Adapter RDK User Guide, Version 0.5 7 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 CCG2 18W Power Adapter RDK User Guide, Version 0.5 8 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. CCG2 18W Power Adapter RDK User Guide, Version 0.5 9 Demonstration Figure 2-3. Charging status in MacBook CCG2 18W Power Adapter RDK User Guide, Version 0.5 10 Demonstration 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. CCG2 18W Power Adapter RDK User Guide, Version 0.5 11
