2.1 Board Description
TEA2017DB1580 240 W 12 V 20 A power supply demo board can operate at a mains input voltage between 90 V (RMS) and 264 V (RMS; universal mains). It contains three sub circuits:
- A DCM/QR/CCM-type PFC converter
- A resonant LLC-type HBC converter
- An SR resonant LLC-type output stage
The purpose of the demo board is to show and evaluate the operation of the TEA2017 PFC + LLC controller and the Synchronous Rectifier TEA2025T in a single output voltage power supply, which includes the operation modes in a typical design. The performance passes general standards, including the EuP lot6 requirements.

2.2 Additional Board Support
In addition to the normal TEA2017 ICs, NXP Semiconductors provides special IC versions for product development. The difference is that the development IC samples have a dedicated I²C interface for easy modification of settings while the IC is operating (“on the fly” changing). The TEA2017DB1580 demo board uses the development version of the TEA2017.
Refer to UM11397, UM11235, UM11657, UM11527 and the Ringo TEA2017 software for additional details on the featured components and board configuration.
2.3 USB-I²C Programming Interface
The USB-I²C programming interface enables setting TEA2017 controller parameters from a computer. The available Ringo TEA2017 development software provides a graphical user interface (GUI) that can be installed on a computer.
The interface and software are intended for engineering work in a lab environment as part of power supply development. It is not suitable for use by consumer or industrial purpose.
2.4 IC Programming Board
This board can be used for programming small series of TEA2017 and/or TEA2016 samples. Place the jumper on the board in the position that corresponds with the IC to be programmed.
By connecting both the 3-pin and 6-pin connector to the USB-I²C programming interface, regular production samples and development samples can be programmed after selecting the correct channel with the switch on the USB-I²C interface.
3. Get Software
3.1 Installing Software
Download the zip file with Ringo TEA2017 software to a folder on your computer and unzip the file.
For the Ringo software to work, the FT232H driver for the USB-I²C programming interface needs to be installed. This installation happens automatically when you connect the interface for the first time via USB. If the driver is not installed automatically, you can use the included drivers to do this manually.
Important: When the FT232H driver is not installed, the Ringo software does not work.
The Ringo program needs no installation. It can be started by double-clicking on Ringo.exe. Keep the other files and folders in the same directory because Ringo makes use of it.
4. Configure Hardware
4.1 Power Supply Setup
The TEA2017DB1580 demo board contains a TEA2017dev sample that can communicate via I²C during operation. It is connected to the interface with a 3-pin connection.
4.2 IC Programming Board Setup
Connecting a IC programming board to the USB-I²C programming interface with a 6-pin cable provides reading or programming for regular TEA2017 production ICs.
If a TEA2017 development IC version is used, then connect the 3-pin cable as well.
The switch on the USB-I²C programming interface selects the 3-pin or 6-pin connection.

Support
Ringo Software
Q: Ringo.exe does not start.
- A1: The USB-I²C interface driver (FT232) needs to be installed on the computer to enable Ringo software to work.
- A2: Make sure you are using a compatible version.
- A3: Ringo is made for Windows operating systems. On other operating systems you can run it via a windows emulator.
- A4: It may be needed to connect the USB-I²C interface again (one time) after a Windows update .
Q: Can I work with Ringo without the interface connected?
- A1: Yes, when the USB-I²C interface driver (FT232) is already installed.
- A2: To get started the USB-I²C interface driver (FT232) needs to be installed on the computer to enable Ringo software to work. For this the interface needs to be connected (one time) to install the driver.
Q: When I connect the USB-I²C interface it does not work.
- A1: A driver is needed to make the FT232 module operational. The driver is often automatically installed (plug and play) but sometimes a manual install is required. Several drivers are included in the Ringo zip package. Watch the video installing USB driver manually.
- A2: When you installed the driver and still it does not work: completely remove the driver ('delete the driver software for this device') and select another driver included or visit the FTDI chip website for more information or driver versions.
USB - I²C Interface
Q: Can I change settings in an TEA2017dev (development type) IC on the power supply when the power supply is not running?
- A1: Yes. When you apply a low mains voltage of 50 Vac the IC is supplied by the HV source and can communicate via I²C. But the power supply does not start because the mains voltage is still too low.
- A2: Yes. If you (temporarily) connect an external power supply of 20 V to SUPIC, the IC is operational without starting the power supply.
Q: Can I change settings in a TEA2017 IC (non development type) on the power supply?
- Yes, but it is more complicated. Application note AN13140 shows how to do it in section 15.5.3.3. You cannot make changes during operation because the pins for I²C communication have a different function during operation.
Q: There is no communication with the IC.
- A1: Check if the switch on the interface is in the correct position: "development version" or "normal version"
- A2: Check if the correct cable is connected (or both when using the programming board)
- A3: Check if signal disturbance is blocking communication
Q: I want to make a modification or repair on the board. Is there a circuit diagram?
- A1: The circuit diagram is included in User Manual UM11397. This document is available in the help tab of Ringo.
Q: What is the function of the LEDs on the board?
- A1: The Ringo software can use them for indicating that the I²C connection is OK. The indication differs between Ringo versions. In general, slow blinking indicates no communication with the IC and fast blinking indicates correct communication with the IC.
Programming Board
Q: Which cable do I need to connect when I want to work with the programming board?
- A1: Connect both 3-pin and 6-pin cables and select the correct I²C channel for communication.
- A2: For a standard TEA2016 /TEA2017 IC, only the 6-pin cable connection is required.
- A3: For a TEA2016 or TEA2017 development IC, both 3-pin and 6-pin cables are required.
Q: I want to measure signals or make a modification on the board. Is there a circuit diagram?
- A1: The circuit diagram is included in the Ringo help tab.
Working With Only The TEA2017DB1580 Demo Board
Q: Can I also work with TEA2017 without buying the I²C interface and the programming board?
- A1: Yes, you can use the TEA2017 IC in a power supply as with other IC types. In this case you make use of the standard IC parameter settings.
- A2: When you want to modify TEA2017 settings to optimize your design, you need the TEA2017 Ringo software and an interface board.
