XRP9710EVB-DEMO-1 Dual Output Digital PWM/PFM Demo Board Programmable Power Management System December 2013 Rev. 1.0.0 GENERAL DESCRIPTION EVALUATION BOARD MANUAL The XRP779710EVB-DEMO-1 board is a complete, two channel power system. The default configuration provides 1.8V and 2.5V at maximum loads of 6Amps per output. The supplies can be dynamically adjusted in 5mV increments. The order and ramp rates for each supply can be programmed to accommodate any sequencing requirement. All power supply operations can be controlled over an I2C interface. Faults, output voltages and currents can also be monitored. Two GPIO and three PSIO signals are available and can be programmed to provide a variety of functions. Unused GPIO/PSIO pins can be programmed as I/O expansion for a microcontroller. The board is supported by PowerArchitectTM 5.1 or later, and plugs directly onto the interposer board acting as an interface to Arduino controller.

ORDERING INFORMATION Refer to XRP9710's datasheet and/or www.exar.com for exact and up to date ordering information. (c) 2013 Exar Corporation 4/19 Rev. 1.0.0 XRP9710EVB-DEMO-1 Dual Output Digital PWM/PFM Demo Board Programmable Power Management System Load the PowerArchitectTM 5.1 software and run it. USING THE EVALUATION BOARD INPUT VOLTAGE RANGE After selecting the proper family (Modules) and the device (XRP9710), select the "Get Started with the EVB-DEMO-1" option when prompted as shown below. The input voltage range of XRP9710EVBDEMO-1 board is from 5.5V to 22V. The default configuration has been optimized for a 12V input rail. When running the board at an input voltage other than 12V, use PowerArchitectTM 5.1 (PA5.1) to evaluate the system performance. I2C INTERFACE The XRP9710 programmable power module employs a standard I2C interface. Although the I2C signals can be pulled up to LDO5 on board by means of installing jumpers at the locations JP1, JP2 and JP4, the I2C bus signals are pulled up on the controller interface board by default (refer to Appendix - jumpers installed shorting pins 2 and 3 together at the locations JP6 and JP7). When done, click "Create". PA 5.1 will load the default XRP9710EVB-DEMO-1 configuration automatically. OPERATING THE EVALUATION BOARD The XRP9710EVB-DEMO-1 is designed to be powered from either an AC/DC wall wart (the output voltage must be in the range of 5.5V to 22V) connected to the barrel connector or a test bench DC power supply (the voltage must be in the range of 5.5V to 22V) connected to the VIN connectors. Apply power to the board. Please refer to the sections above on how to properly supply power to the board and what voltage range to use. Turn on the Power supply. Use USB cable to connect the computer (type A) and the Arduino controller board (type B). BRING UP PROCEDURE Plug the XRP9710EVB-DEMO-1 evaluation board to the controller interface board as shown below. (c) 2013 Exar Corporation Go to the Tools tab in PA 5.1 and select Boards. The software will identify communication ports where it found the Arduino controller board. Select the port. 5/19 Rev. 1.0.0 XRP9710EVB-DEMO-1 Dual Output Digital PWM/PFM Demo Board Programmable Power Management System PA 5.1 is now communicating with the Arduino controller board which is indicated in the lower left corner. PA 5.1 will go through the process of loading configuration in the flash. Once it has successfully completed the task, it will report the outcome as seen above and reset the device if "Automatically Reset After Flashing" box checked (default option). Programming the Configuration onto XRP9710 To program a configuration go to the Tools tab in PA 5.1 and select Program Flash. Close the window. Note that XRP9710EVB-DEMO-1 boards will be pre-loaded with the default configuration. Regulation To enable channel regulation go to the Tools tab in PA 5.1 and select Dashboard. The program Flash window will appear. In Dashboard turn Group 1 on. The configuration groups the channels 3 and 4 into Group 1. The channels are now in regulation as indicated by VOUT readings as well as the inregulation indicators. Click the Flash button. (c) 2013 Exar Corporation 6/19 Rev. 1.0.0 XRP9710EVB-DEMO-1 Dual Output Digital PWM/PFM Demo Board Programmable Power Management System EVALUATION BOARD CONNECTIONS The following picture illustrates how VIN supplied from a test bench DC power supply and instruments attached to the outputs would be connected to the XRP9710EVB-DEMO-1 board. Channels can be turned on individually if desired. GPIO and PISO interface The GPIOs, PSIOs and ENABLE can be controlled from the Arduino controller dynamically in the dashboard. ENABLE signal is connected to the Arduino controller board by default (JP3 header is shorted). Arduino drives the ENABLE pin low to place XRP9710 into the shutdown mode. It releases the ENABLE pin to enable the device. If leaving the ENABLE pin floating is desired, the jumper at JP3 shall be removed. The PSIOs are not pulled up on XRP9710EVBDEMO-1 by default. There is a loading option to pull PSIOs up to LDO5 if desired. To do this, one will need to short JP4, JP5, JP6 and JP7 headers by means of installing jumpers.
