ORDERING INFORMATION Refer to XRP9710’s datasheet and/or www.exar.com for exact and up to date ordering information. © 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. © 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. © 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. © 2013 Exar Corporation 7/19 Rev. 1.0.0 1 2 3 4 5 6 EVALUATION BOARD SCHEMAITCS A A N0VIN0IC VIN_IC 0 C7 50V 10UF T15 N0LDO5V LDO5V 12 P0U102727 PVINP0U1028 28 PVINP0U1032 32 PVIN P0U103333 PVIN 2 1 P0T900 0805 P0KB102 VCC GND P0JP401 P0JP402 JP4 N05V 5V C5 50V 10UF GND C2 50V 1UF P0U1012 0805 P0C202 P0C201 P0T1500 GND GND 1210 P0R102 P0C502 P0C501 P0R101 1206 1210 P0C702 P0C701 N0VIN VIN R1 P0T1200 T12 P0T1700 T17 34 U1 XRP9710 Module 6 P0U106 NC 7 P0U107 P0U1034 LDO5V NC KB1 8 P0U108 NC P0KB101 Pad - Not Part N0ENABLE ENABLE 11 T9 P0U1011 ENABLE NC 9 P0U109 10 P0U1010 NC XRP9710 N0VOUT30P VOUT3_P 15 P0U1015 VOUT3_P NC N0VOUT30N VOUT3_N 16 P0U1016 VOUT3_N NC N0VOUT40P VOUT4_P 17 P0U1017 VOUT4_P NC N0VOUT40N VOUT4_N 18 P0U1018 NC N0LDO5V LDO5V 2 VOUT3 N0VOUT3 VOUT3 KB2 P0KB201 KB3 N0VOUT30P VOUT3_P P0KB202 P0T300 T3 P0T700 T7 0805 P0KB301 P0KB302 N0VOUT30N VOUT3_N Pad - Not Part 0805 C20 DNS 2 test point VOUT4 N0VOUT4 VOUT4 0805 P0KB502 0805 C10 DNS P0TP602 TP6 Pad - Not Part TP2 test point 0805 P0KB402 N0VOUT40P KB5 VOUT4_P P0KB501 Pad - Not Part KB4 P0KB401 N0VOUT40N VOUT4_N P0T2200 T22 P0T2100 T21 Pad - Not Part 1 P0TP501 C13 50V 0.01F C19 + 50V 0.1UF test point 2 P0TP502 P0C2002 P0C2001 P0TP601 1 T19 C8 10V 47uF P0C100N P0C100P C6 10V 47uF P0T1900 0603 P0T2000 PGND3 P0C1902 P0C1901 T20 GND P0C801 SDA T14 1210 P0U1021 22 P0U1022 SCL N0LX4 LX4 P0T1400 P0C802 37 LX4 P0U1040 40 LX4 P0U1044 44 LX4 P0U1041 41 PVOUT4 P0U1045 45 PVOUT4 P0U1038 38 PGND4 P0U1037 P0C601 PSIO2 P0TP102 1 C11 C1 DNS DNS 0805 P0C1102 P0C1101 P0TP101 C12 + 50V 0.1UF 1P0TP201 T8 C3 10V 47uF 2P0TP202 C4 10V 47uF P0T800 P0U1043 13 14 35 36 39 N0SCL SCL P0T400 1210 21 50V P0C602 N0SDA SDA PSIO1 0402 43 P0U1042 T4 P0C1301 P0C1302 PSIO2 N0PSIO2 PSIO0 AGND AGND P0U1035 AGND P0U1036 AGND P0U1039 AGND 42 P0U1023 0402 T11 P0C10N P0C10P 23 GPIO1 N0LX3 LX3 P0T1100 B TP1 0603 N0PSIO0 PSIO0 P0U1029 29 LX3 P0U1030 30 LX3 P0U1031 31 LX3 P0U1024 24 PVOUT3 P0U1025 25 PVOUT3 P0U1026 26 PGND3 P0C1202 P0C1201 P0U1020 1210 20 GPIO0 N0LDO5V LDO5V 0.01F P0C1502 P0C1501 P0C302 P0C301 N0GPIO1 GPIO1 P0T1000 N0PSIO1 PSIO1 5 P0U105 1210 P0U1019 P0U1014 T10 4 P0C402 P0C401 19 P0U1013 T6 3 P0U103 C15 N0GPIO0 GPIO0 P0T600 2 P0U102 P0U104 VOUT4_N NC B 1 P0U101 GND TP5 test point PGND4 GND N0VOUT30P VOUT3_P N0VOUT30N VOUT3_N N0VOUT40P VOUT4_P 1P0TP301 D1 DNS GND GND GND 0402 C16 16V 0.1UF P0C1402 P0C1401 0402 C17 16V 0.1UF P0C1602 P0C1601 0402 C18 16V 0.1UF P0C1702 P0C1701 1 3 2 P0P202 P2 P0P203 0402 P0C1802 P0C1801 2 P0D102 C9 35V 120uF N0VOUT40N VOUT4_N P0P201 2P0TP302 P0C902 C P0D101 P0C901 N0VIN VIN test point P0TP402 P0TP401 1 TP4 C14 16V 0.1UF C GND test point GND TP3 N05V 5V N05V 5V N05V 5V T23 P0T2300 JP7 Header 2X10 N0PSIO0 PSIO0 N0PSIO1 PSIO1 GND JP6 2 P0JP202 1 P0JP201 JP5 P0R801 0805 2 P0JP102 1 P0JP101 JP2 P0R802 P0R201 0603 P0R202 P0R301 0603 P0R501 0603 2 P0JP502 1 P0JP501 R8 1.2K 1 GND 2 P0JP602 1 P0JP601 R2 4.7K P0DS101 JP3 2 P0JP702 1 P0JP701 N0PSIO2 PSIO2 N0PSIO0 PSIO0 R3 4.7K JP1 2 N0PSIO1 PSIO1 R5 4.7K P0DS102 N05V 5V N0VIN VIN R6 4.7K P0R302 2P0JP302 1P0JP301 N0ENABLE ENABLE R7 4.7K P0R502 P0R402 0603 0603 P0R401 N0GPIO0 GPIO0 N0GPIO1 GPIO1 P0R602 DNS 1 P0P101 3 P0P103 5 P0P105 7 P0P107 R9 DNS 9 P0P109 P0R9010805 P0R902 11P0P1011 13P0P1013 15P0P1015 17P0P1017 19P0P1019 P0R701 P0P104 0603 R4 N05V 5V 2 4 P0P106 6 P0P108 8 P0P1010 10 P0P1012 12 P0P1014 14 P0P1016 16 18 P0P1018 P0P1020 20 P0P102 P0R702 N0SCL SCL N0SDA SDA P0R601 P1 P0T1800 T18 P0T1600 T16 T2 N0PSIO2 PSIO2 P0T1300 T13 T5 N0SDA SDA N0SCL SCL GND P0T500 T1 GND P0T200 DS1 P0T100 GND D D 8/19 Title XRP9710EVB-DEMO-1 EXAR 48720 Kato Road Size: C Rev: 1.0 Name:XRP9710EVB-DEMO-1.SchDoc Fremont, CA 94538 Date: 11/12/2013 Time: 1:14:10 PM Sheet 1 of 1 www.exar.com File: C:\SVN_LOCAL\XRP9711_temp_char_board\XRP9710EVB-DEMO-1\board\XRP9710EVB-DEMO-1.SchDoc 1 2 3 4 5 6 XRP9710EVB-DEMO-1 Dual Output Digital PWM/PFM Demo Board Programmable Power Management System BILL OF MATERIAL Ref.
