It is configured to provide 3.3V, 2.5V 1.5V and 1V at a maximum of 3A, 3A, 5A and 10A loads respectively. The 1.5V and 1V supplies can be adjusted in 2.5mV increments, the 2.5V supply in 5mV increments, and the 3.3V supply is adjustable in 10mV 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 an Arduino controller or Exar’s XCM.

INPUT VOLTAGE RANGE The input voltage range of these boards is from 5.5V to 25V. The power components have been optimized for a 12V input rail. When running the board at an input voltage other than 12V, use PowerArchitectTM 5.1 to evaluate the system performance. After selecting the proper family (Chips) and the device (XRP7724 or XRP7725), select the “Get Started with the EVB-DEMO2” option when prompted as shown below. I2C INTERFACE The XRP7724 and XRP7725 programmable power controllers employ a standard I2C interface. Although the I2C signals can be pulled up to LDO5 on board by means of installing resistors at the locations R25 and R26, the I2C bus signals are pulled up on the controller interface board (XR77EVB-INT-1) by default (refer to Appendix – jumpers installed shorting pins 2 and 3 together at the locations JP6 and JP7). OPERATING THE EVALUATION BOARD When done, click “Create”. PowerArchitectTM 5 will load the default configuration automatically. The XRP7724/7725EVB-DEMO-2 is designed to be powered from either an AC/DC wall wart (the output voltage must be in the range of the controllers - 5.5V to 25V) connected to the barrel connector or a test bench DC power supply (the voltage must be in the range of the controllers - 5.5V to 25V) 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 XRP7724/7725EVB-DEMO-2 evaluation board and the Arduino board into the controller interface board as shown below. © 2014 Exar Corporation Go to the Tools tab in PA 5 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 XRP7724/7725EVB-DEMO-2 Quad Channel Digital PWM/PFM Demo Board Programmable Power Management System PA 5 is now communicating with the Arduino controller board which is indicated in the lower left corner. PA 5 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 XRP7724/7725 Close the window. To program a configuration go to the Tools tab in PA 5 and select Program Flash. Note that XRP7724/7725EVB-DEMO-2 boards will be pre-loaded with the default configuration. Regulation To enable channel regulation go to the Tools tab in PA 5 and select Dashboard. The program Flash window will appear. In Dashboard turn Group 1 and Group 2 on. The configuration groups the channels 1 and 2 into the group 1, and the channels 3 and 4 into the group 2. The channels are now in regulation as indicated by VOUT readings as well as the in-regulation indicators.

To do this, one will need to populate the locations R27, R28, R30. 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 XRP7724/7725EVBDEMO-2 board. Channels can be turned on individually if desired. INTERFACE BOARD CONNECTIONS The following picture illustrates connections on the interface board - XR77EVB-INT-1. Its primary task is to provide interface between the Arduino controller board and EVB. In addition, as explained in the subsequent sections, it can be used to make connection between XCM and EVB using 10-wire ribbon cable. 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 (JP2 header is shorted). Arduino drives the ENABLE pin low to place XRP7724/7725 into the shutdown mode. It releases the ENABLE pin to enable the device. If leaving the ENABLE pin floating is desired, the jumper at JP2 shall be removed. The PSIOs are not pulled up on XRP7724/7725EVB-DEMO-2 by default. There is a loading option to pull PSIOs up to LDO5 if © 2014 Exar Corporation 7/19 Rev. 1.0.0 XRP7724/7725EVB-DEMO-2 Quad Channel Digital PWM/PFM Demo Board Programmable Power Management System USING EXAR CONFIGURATION MODULE (XCM) TO COMMUNICATE WITH THE Wiring XCM directly to the Evaluation Board EVALUATION BOARD Use 3-wire connection between JP4 pins 1-3 on the XCM (pin 1 – SCL; pin 2 – GND; pin 3 – SDA) to the P3 connector on the evaluation board, the pin 8 (GND), the pin 9 (SDA) and the pin 10 (SCL) on the interface board. Make a use of the silkscreen labels on both boards. It is possible to use the XCM (firmware version v62) to communicate with the XRP7724/7725EVB-DEMO-2 board. PA 5 supports XCM. The main task will be connecting XCM to the evaluation board. Using Interface Board If the interface board is available use following steps: • • • • • • Make sure no Arduino controller board is connected to the interface board Remove I2C pull-up jumpers at location JP6 and JP7 (need to be open in all positions) If the 10-wire ribbon cable is available connect the XCM to the interface board as shown below Use I2C pull-up resistors on XCM (install headers at the locations JP2 and JP3 shorting pins 2 and 3) If 10-wire ribbon cable is not available use 3-wire connection between JP4 pins 1-3 on XCM (pin 1 – SCL; pin 2 – GND; pin 3 – SDA) to test points T23 (SCL), T24 (GND) and T25 (SDA) on the interface board. Make a use of the silkscreen labels on both boards. Connect the interface board and the evaluation board as shown above. © 2014 Exar Corporation 8/19 Rev. 1.0.0 0 P0T500 P0R1602 T5 N0VCC VCC R5 DNS P0R501 0805 P0R502 3 N0LDO5 LDO5 4 5 C38 DNS P0T600 50V 0603 C11P0C1101 P0C1102 0.1UF N0LX1 LX1 GC1 P0OUT101 2 P0T200 P0T1800 P0T2202 0603 0603 P0OUT201 2 P0T300 GND D N0SDA SDA SCL N0SCL N0PSIO0 PSIO0 N0PSIO1 PSIO1 N0PSIO2 PSIO2 ENABLE N0ENABLE JP2 T16 ENABLE N0ENABLE P0T1600 DNS N0PSIO0 PSIO0 DNS P0R2501 0603 P0R2601 0603 R26 P0R2502 DNS P0R4101 P0R4001 P0R3001 DNS R41 0603 DNS R40 0603 DNS DNS N0PSIO2 PSIO2 N0PSIO0 PSIO0 P0OUT301 2 P0T2000 P0T1200 P0T2602 0603 P0R2901 P0R1302 0603 P0R2902 P0C2802 P0C2801 0805 P0OUT401 R15 P0T1500 GND4 P0GND401 T14 GND GND R25 DNS N0SDA SDA N0SCL SCL N0PSIO2 PSIO2 GND D N0GPIO0 GPIO0 GND N0GPIO1 GPIO1 GND 9/19 2 T21 R34 DNS PSIO1 N0PSIO1 Header 2X10 Header 15 1 N0VOUT4 VOUT4 P0T2100 0603 P0R3401 P0R1502 C36 50V 1UF T17 P0T1700 N0LDO5 LDO5 P0R2602 P0R4401 R30 0603 0805 P0R4402 P0R2801 R44 R28 P0R4102 P0JP201 R27 P0R4002 N0LDO5 LDO5 N0LDO3V3 LDO3V3 N0PSIO1 PSIO1 P0JP202 N0GPIO0 GPIO0 N0GPIO1 GPIO1 P0R3002 2 1 P0R3102 1 P0P101 3 P0P103 5 P0P105 7 P0P107 9 P0P109 11P0P1011 13P0P1013 15P0P1015 17P0P1017 19P0P1019 0603 0603 P0P104 P0R2802 P0R3101 2 4 P0P106 6 P0P108 8 P0P1010 10 12 P0P1012 14 P0P1014 P0P1016 16 P0P1018 18 P0P1020 20 P0P102 P0R2701 DNS P0R2702 N0GPIO0 GPIO0 N0GPIO1 GPIO1 N0LDO5 LDO5 R31 N0LDO5 LDO5 P1 N0SCL SCL N0SDA SDA 2 P0R1501 T13 C32 10V 47uF 0603 DNS C35 DNS N0CH40OUT CH4_OUT Pad -
