GENERAL DESCRIPTION The XRP7720/7724/7725EVB-DEMO-1 board is a complete, four channel, power system. It provides 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 and plugs directly onto the Exar Communications Module (XRP77xxEVB-XCM).

XRP7720-DEV PIN DESCRIPTION

Name Pin Number Description

VCC 41 Input voltage. Place a decoupling capacitor close to the pin. This input is used in UVLO fault generation.

DVDD 16 1.8V supply for digital circuitry. Connect pin to AVDD. Place a decoupling capacitor close to the pin.

VCCD1-2 VCCD3-4

23,34

Gate Drive supply. Two independent gate drive supply pins where pin 34 supplies drivers 1 and 2 and pin 23 supplies drivers 3 & 5. One of the two pins must be connected to the LDO5 pin to enable two power rails initially. It is recommended that the other VCCD pin be connected to the output of a 5V switching rail(for improved efficiency or for driving larger external FETs), if available, otherwise this pin may also be connected to the LDO5 pin. A bypass capacitor (>1uF) to PAD is recommended for each VCCD pin with the pin(s) connected to LDO5 with shortest possible etch.

AGND 2 Analog ground pin. This is the small signal ground connection.





GL_RTN1-4 39,33, 28,22 Ground connection for the low side gate driver. This should be routed as a signal trace with GL. Connect to the source of the low side MOSFET.

GL1-GL4 38,32, 27,21 Output pin of the low side gate driver. Connect directly to the gate of an external N-channel MOSFET.

GH1-GH4 36,30, 25,19 Output pin of the high side gate driver. Connect directly to the gate of an external N-channel MOSFET.

LX1-LX4 37,31, 26,20

Lower supply rail for the GH high-side gate driver. Connect this pin to the switching node at the junction between the two external power MOSFETs and the inductor. These pins are also used to measure voltage drop across bottom MOSFETs in order to provide output current information to the control engine.

BST1-BST4 35,29, 24,18

High side driver supply pin(s). Connect BST to the external capacitor as shown in the Typical Application Circuit on page 5. The high side driver is connected between the BST pin and LX pin and delivers the BST pin voltage to the high side FET gate each cycle.

GPI0-GPIO1 9,10 These pins can be configured as inputs or outputs to implement custom flags, power good signals, enable/disable controls and synchronization to an external clock.

PSIO0-PSIO2 13,14,15

Open drain, these pins can be used to control external power MOSFETs to switch loads on and off, shedding the load for fine grained power management. They can also be configures as standard logic outputs or inputs just as any of the GPIOs can be configured, but as open drains require an external pull-up when configured as outputs.

SDA, SCL 11,12 SMBus/I2C serial interface communication pins. These pins can be configured open drain or pseudo-TTL requiring a pull-up resistor.

VOUT1-VOUT4 5,6,7,8 Connect to the output of the corresponding power stage. The output is sampled at least once every switching cycle

LDO5 44 Output of a 5V LDO. This is a micro power LDO that can remain active while the rest of the IC is in the stand-by mode. This LDO is also used to power the internal Analog Blocks.

ENABLE 40

If ENABLE is pulled high or allowed to float high, the chip is powered up (logic is reset, registers configuration loaded, etc.). The pin must be held low for the XRP7724 to be placed into shutdown. Active channels will automatically be ramped down, if desired, prior to the disabling of the chip.

DGND 17 Digital ground pin. This is the logic ground connection, and should be connected to the ground plane close to the PAD.

NC 1,3,42 No Connect

DGND 17 Digital ground pin. This is the logic ground connection, and should be connected to the ground plane close to the PAD.

CPLL 3 PLL compensation capacitor

ORDERING INFORMATION Refer to XRP7720/XRP7724/XRP7725 datasheets and/or www.exar.com for exact and up to date ordering information.





USING THE EVALUATION BOARD

INPUT VOLTAGE RANGE The input voltage range of these boards is from 5.5V to 18V. 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.

I2C INTERFACE The controller employs a standard I2C interface. Pull-ups for the I2C signals are included on the demo board.

OPERATING THE EVALUATION BOARD The demo board is designed to be powered from either an AC/DC wall wart (the output voltage must be in the range of the controller VCC specification – 5.5V to 18V) connected to the barrel connector, or a test bench DC power supply (the voltage must be in the range of the controller VCC specification – 5.5V to 18V) connected to the Vin phoenix connector (the positive side is indicated with VIN text in silkscreen. The proper connection is indicated in the evaluation board connections section below).

BRING UP PROCEDURE Plug the demo board to the XCM as shown below.

Load the PowerArchitectTM 5.1 software and run it.

After selecting the proper family (Chips) and the device (XRP7720, XRP7724, or XRP7725), select the “Get Started with the EVB-DEMO-1” option when prompted as shown below.

When done, click “Create”. PowerArchitectTM

5.1 will load the default configuration automatically.

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.

Insert the USB cable into the computer and the XCM board.

Go to the Tools tab in PowerArchitectTM 5.1 and select Boards. The software will identify communication ports where it found the XCM board. Select the port.

PowerArchitectTM 5.1 is now communicating with XCM which is indicated in the lower left corner.




Programming the Configuration onto XRP7720-DEV/XRP7724/XRP7725

To program a configuration go to the Tools tab in PowerArchitectTM 5.1 and select Program Flash.

The program Flash window will appear.

Click the Flash button.

PowerArchitectTM 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). Close the window. Note that the boards will be pre-loaded with the default configuration.

Regulation To enable channel regulation go to the Tools tab in PowerArchitectTM 5.1 and select Dashboard.

In Dashboard turn Group 1 and Group 2 on. The configuration groups channel 1, channel 2, and LDO3.3* into Group 1, and channels 3 and 4 into Group 2. The channels are now in regulation as indicated by Vout readings as well as the in-regulation indicators. Note*: Not available in XRP7720EVB-DEMO-1




Channels can be turned on/off individually if desired.

Note: Make sure there is a jumper shorting JP1 pins 1 and 2 installed on your board. Channel 4 will not regulate without it.
