DEMO MANUAL DC2023A 16-Channel Power Supply System Featuring the LTM2987 Power System Manager Description The DC2023A is a demonstration system for the LTM®2987 16-channel I2C/SMBus/PMBus power system manager with EEPROM. The LTM2987 monitors and controls 16 power supply rails. The DC2023A demonstrates the ability of the LTM2987 to sequence, trim, margin, supervise, monitor, and log faults for 16 power supply rails. Each power supply channel’s output voltage is monitored and the LTM2987 monitors its own internal die temperature. The DC2023A is a single circuit board that contains sixteen independent power supply rails. The board employs sixteen LTC®3405A 300mA switch-mode regulators, which are configured to be controlled by the LTM2987. The LTM2987 is available in a µModule® (micromodule) package and contains two LTC2977 devices. This board provides a sophisticated 16-channel digitally programmable power supply system. The rail voltages are programmable within the trim range shown in the Performance Summary. This demonstration system is supported by the LTpowerPlay™ graphical user interface (GUI) that enables complete control of all the features of the LTM2987. Together, the LTpowerPlay software and DC2023A hardware system create a powerful development environment for designing and testing LTM2987 configuration settings. These settings can be stored in the device’s internal EEPROM or in a file. This file can later be used to order pre-programmed devices or to program devices in a production environment. The software displays all of the configuration settings and real time measurements from the LTM2987. Telemetry allows easy access and decoding of the fault log created by the LTM2987. The board comes pre-programmed with the EEPROM values appropriate for the sixteen power supplies used on the DC2023A. Just plug and play! Multiple DC2023A board sets can be cascaded together to form a high channel count power supply (see MultiBoard Arrays). This cascaded configuration demonstrates features of the LTM2987 which enable timing and fault information to be shared across multiple ICs. The user can configure up to eight DC2023A boards, thereby controlling up to 128 separate power supply rails. Larger arrays of LTM2987s are supported through programmable I2C base address or bus segmentation. The DC2023A demo board can be powered by an external power supply, such as a +12VDC supply. Communication with the software is provided through the DC1613 USB-toI2C/SMBus/PMBus Controller.

The software supports a variety of different tasks. You can use LTpowerPlay to evaluate Linear Technology ICs by connecting to a demo board system. LTpowerPlay can also be used in an offline mode (with no hardware present) in order to build a multi-chip configuration file that can be saved and reloaded at a later time. LTpowerPlay provides unprecedented diagnostic and debug features. It becomes a valuable diagnostic tool during board bring-up to program or tweak the power management scheme in a system or to diagnose power issues when bringing up rails. LTpowerPlay utilizes the DC1613 I2C/SMBus/PMBus Controller to communicate with one of many potential targets, including the DC2023A demo system or a customer board. The software also provides an automatic update feature to keep the software current with the latest set of device drivers and documentation.

Figure 1. Screen Shot of the LTpowerPlay GUI dc2023afa 3 DEMO MANUAL DC2023A Quick Start Procedure The following procedure describes how to set up a DC2023A demo system. 1.Download and install the LTpowerPlay GUI: http://www.linear.com/ltpowerplay 6.Launch the LTpowerPlay GUI. a. The GUI automatically identifies the DC2023A and builds a system tree. The system tree on the left hand side should look like this: 2.Remove the board from the ESD protective bag and place it on a level surface. Connect the DC1613 I2C/SMBus/PMBus Controller to the DC2023A board using the 12-pin ribbon cable. 3.Confirm that the CONTROL switch is set to the RUN position. 4.Plug the USB to I2C/SMBus/PMBus Controller into a USB port on your PC. The board should power up with all power good LEDs and +5V LED illuminated green. The USB-to-I2C/SMBus/PMBus Controller supplies ~100mA of current which should be sufficient for a single demo board. 5.If multiple boards are being powered, connect a +12VDC power supply with > 0.5A capacity to the VIN input jack of the DC2023A. Note: For multiple board arrays, the GUI automatically ensures each device has a unique address. In this scenario, it is recommended at this point to store these addresses to NVM (EEPROM) by clicking the “RAM to NVM” icon in the toolbar. Figure 2. Connecting DC2023A board and the DC1613 I2C/SMBus/PMBus Controller dc2023afa 4 DEMO MANUAL DC2023A Quick Start Procedure b.A green message box will be displayed for a few seconds in the lower left hand corner confirming that the DC2023A is communicating: 7.The CONTROL switch is configured to control all 16 channels. Slide the switch to RUN to enable, OFF to disable all channels. For multiple board arrays, the CONTROL switch is wired to a signal that is common across all boards. All CONTROL switches must be set to the RUN position to enable all boards. Loading a DC2023A Configuration (*.Proj) File with the GUI c. Save the demo board configuration to a (*.proj) file by clicking the "Save" icon. This creates a backup file. Name it whatever you want. 1.In the upper left hand corner of the GUI, File > Open > browse to your *.proj file. This will load the file into the GUI. 2.Click on the “Go Online” icon, then click on the “PC->RAM” arrow. This loads the configuration into the working RAM of the LTM2987. 3.To store the configuration to NVM (EEPROM), click on the “RAM->NVM” icon. Figure 3. DC2023A Top Side Details dc2023afa 5 DEMO MANUAL DC2023A Common Demo Board Operations Margin All Rails The LTM2987 power manager on the DC2023A not only monitors each of the sixteen outputs but can margin the outputs either high or low. Margining is the operation that moves a rail either up or down for testing purposes. It allows a system to be fully characterized over supply limits without the use of external hardware or resources. The GUI provides an easy way to margin all rails high or all low by clicking one of four buttons. To invoke the margining dialog, click the GroupOp icon in the toolbar. The buttons labeled “ignore faults” will margin without creating a fault even if the fault limits are exceeded. Each LTC2977 inside the module has a multiplexed ADC that is used to provide voltage, current, and temperature readback values. The telemetry plot in the GUI is similar to a multi-channel oscilloscope which is capable of displaying any parameter that is displayed in the telemetry window. Due to the nature of a multiplexed ADC converter, it has an associated ADC loop time. The total ADC loop time (~100ms to 160ms) for a given channel is dependent on the device’s configuration. Refer to the LTM2987 data sheet for complete ADC timing specifications. Creating a Fault There is a pushbutton on the DC2023A board that is used to force a fault and demonstrate the demo board’s ability to detect it and respond according to the configuration. When depressed, the pushbutton creates a fault on channel 10, the 2.5V output (GUI channel U1:2). The user should see all outputs power off, the fault LED momentarily illuminate, the alert LED illuminate continuously, and all rails sequence back on after a retry period. The user may also short any power supply output indefinitely. This is a good way to induce UV faults and shows that a shorted channel will not be damaged. Use a jumper wire or a coin to short any output. A look at the telemetry window shows the effect of the margin high or margin low operation. The following screen shot shows all rails going from nominal set points to margin high, margin low, and back to nominal voltages. dc2023afa 6 DEMO MANUAL DC2023A Common Demo Board Operations The LTM2987 has a feature which allows it to sequence its channels off in a controlled manner, as opposed to turning all rails off immediately. The SequenceOffOnFault bit in the MFR_CONFIG_LTC2977 register sets this behavior on each channel. The DC2023A demo board has been configured to sequence off all channels when a fault occurs. Pressing the “CREATE FAULT” pushbutton causes the FAULT pin to be asserted low which triggers all rails to power down based on the TOFF_DELAY times. Clearing a Fault To clear a fault, the user may click the CF icon in the GUI or simply push the RESET pushbutton on the demo board. In both cases, the red (+) on the CF icon and alert LED on the board will be cleared. You will notice that all rails are automatically re-enabled after a programmable retry period. The alert LED may be cleared by pushing the Clear Faults (CF) icon in the GUI. After clearing faults, the system tree may remain “yellow” if any non-volatile fault logs are present. For further information, see the Working with the Fault Log section. Resetting The DC2023A A reset pushbutton is provided on the board. To reset all devices on the DC2023A board and reload the EEPROM contents into operating memory (RAM), press RESET (SW1) on the DC2023A. Figure 4 shows FAULTB asserting low, and each of the channels sequencing off per the TOFF_DELAY settings. Figure 5 shows the same except that the 3.0V rail (CH12) does not have its SequenceOffOnFault bit set. The 3.0V rail powers down immediately as defined by the fault response setting. Figure 4. Sequencing Off (SeqOffOnFault=1) DC2023A LEDs Each individual channel on DC2023A also has its own green “power good” LED (CH0 through CH15). When USB power (DC1613 Controller) or external power (6-14V jack) is applied, the +5V green LED will illuminate, indicating that the LTM2987 is powered. The red LEDs will illuminate when an alert or a fault has occurred. Figure 5. Sequencing Off (SeqOffOnFault=0) dc2023afa 7 DEMO MANUAL DC2023A Common Demo Board Operations Sequencing Output Channels The LTM2987 has been pre-programmed to different TON_DELAY values for each channel. The TON_DELAY parameter is applied to each device relative to its respective CONTROL pin. When multiple demo boards are connected together, all CONTROL pins are wire OR’d. Therefore the TON delays are enforced relative to one edge. The same applies to TOFF_DELAY values. When the CONTROL switch is set to the OFF position, all rails will power down sequentially based on each of the device’s TOFF_DELAY values. Figure 6 shows an oscilloscope screen capture of three output rails sequencing up and down in response to the CONTROL pin. Each channel has an LED which visually indicates if the channel has power. When the CONTROL pin is switched on and off, you will observe the relative on/off timing of the 16 channels. For the LTM2987, the TON_DELAY and TOFF_DELAY values extend to 13.1 seconds, providing very long on and off sequencing of power supply rails. Figure 6. Sequencing Output Channels with DC2023A Using TON_DELAY and TOFF_DELAY Figure 7. TON_DELAY Configuration Figure 8. TOFF_DELAY Configuration dc2023afa 8 DEMO MANUAL DC2023A Common Demo Board Operations Why Am I Off? Tool Use the Why am I Off tool in the LTpowerPlay GUI to diagnose the reason a power supply channel is turned off. The tool can be located in the top right corner of the GUI, next to the Register Information tab. Hover your cursor over this tab to show the tool. Figure 9. Why Am I Off Tool in the LTpowerPlay GUI dc2023afa 9 DEMO MANUAL DC2023A Advanced Demo Board Operations What Is a Fault Log? A fault log is a non-volatile record of the power system leading up to the time of fault. It holds the most recent monitored values (up-time, voltage, current, temperature) that can be analyzed to help determine the cause of the fault. It is a powerful diagnostic feature of the LTM2987 on the DC2023A demo board. Create a Fault and Fault Log To create a fault log, you must create a fault, as described in the Creating a Fault section. If multiple boards are configured, select the appropriate device in the system tree by clicking on the appropriate LTM2987 chip. We will proceed to work with the fault log. Working with the Fault Log Once a fault has occurred, the Fault Log (FL) icon will show a red (+) sign on it, indicating that the GUI has detected a fault log in the device. Clicking the icon will bring up a dialog box. Note that it is context sensitive. Be sure that the desired device is selected in the system tree. Notice that the checkbox “Log to EEPROM on Fault” is checked. Once a fault occurs, the device will automatically write the fault log data to EEPROM (NVM). At this point, the log is locked and will not change until it is cleared by the user. To read the EEPROM log data, first click the “NVM to RAM” button. At this point the RAM Log is locked and not updated even though the telemetry readings continue. Click the “Read RAM Log” button. The log data will appear in the text box below. dc2023afa 10 DEMO MANUAL DC2023A Advanced Demo Board Operations The log contains timestamp, up-time, channel voltage readings, an input voltage reading, an on-chip temperature reading, etc. There will be a number of loops; each loop contains data obtained in one ADC loop time with the most recent ADC loop data on top and the oldest data at the bottom of the log. The up-time indicates, at the time of fault, the amount of time the device has been powered up or time since the previous reset. In this case, the fault log will show that channel U1:2 faulted due to a VOUT_UV_FAULT condition. On the previous telemetry loop, the channel voltage reading was a nominal value (2.5V). Fault Sharing Setup in the GUI Fault sharing provides a means of propagating a fault detected by a power system manager to other power system managers via FAULT pins. Use the Fault Sharing Setup Tool to configure the fault sharing in the GUI. Select the LTM2987 labeled U0 in the system tree. Go to Utilities > Fault Sharing Diagram. For more details on this topic, please refer to the Fault Management section in the data sheet. To clear the fault log, click the “Clear/Rearm EEPROM Log” button. This allows the selected device to be ready for a new fault event. To clear all faults, click the Clear Faults (CF) icon. The fault sharing dialog will appear as shown in Figure 10. All Response and all Propagate switches are closed by default. In this configuration, a fault on one of the LTM2987 channels will shut down all 16 channels, and a fault on any LTM2987 channel will propagate to all channels on the DC2023A demo board since the fault pins are tied together. Note: All FAULT pins on the LTM2987 are tied together on the DC2023A demo board. These pins are open drain and have a common pull-up resistor to provide a logic high level (inactive). All FAULT pins are active low. There are two types of actions to fault conditions: How a channel responds to another channel’s fault and whether a particular channel propagates a fault to other channels. FAULT pins are bidirectional, meaning the device may drive its FAULT pin low (output) or may respond to the FAULT dc2023afa 11 DEMO MANUAL DC2023A Advanced Demo Board Operations pin when another device drives it low (input). Because all FAULT pins are wire OR’d on the DC2023A, this hardware configuration allows one to program each device’s fault settings on a channel-by-channel basis. By default, the LTM2987 is configured to shut down all channels if other devices fault and to broadcast its own fault via the FAULT pins. A fault on these channels will cause only that channel to fault off. You can think of the “Response” switches as “shut this channel down when another channel faults”, and the “Propagate” switches as “drive a fault pin to broadcast to other channels that this channel faulted”. Fault Configuration Example Let’s explore two different examples. Suppose we do not want channel U0:0 (CH0 1.0V rail) to propagate its fault to the other channels when it faults. And suppose we do not want channel U0:1 (CH1 1.1V rail) to shut down in response to another channel’s fault. We can configure the switches as shown in Figure 11. Simply click the switches to open/close. Click OK to close the dialog box. Click the “PC->RAM” icon to write the changes to the DC2023A. We can now create a fault on U0:0 (CH0) by shorting the output to ground. You may use a coin or a jumper to temporarily connect CH0 to the GND turret. You will notice that the channel shuts off but the other channels remain powered up because its fault is not propagated to the other channels. After the retry period, channel U0:0 (CH0) will power back up. We can now observe the effect of changing the response setting on U0:1 (CH1). If you short U0:2 (CH2 1.2V rail) to ground, notice that all rails shut down except U0:1 (CH1). This is an example of a keep-alive channel that remains powered up independent of faults on other channels. Figure 10. Fault Sharing Utility in LTpowerPlay GUI Figure 11. Updated Fault Sharing Configuration Multiple DC2023A boards can be combined to control up to 128 independent power supplies. Eight boards may be cascaded. The number of boards is limited by an I/O expander chip that has three address pins, allowing eight different combinations. This setup demonstrates the coordinated fault responses and accurate time base shared across multiple LTM2987 modules. dc2023afa 12 DEMO MANUAL DC2023A Setup Procedure for Multi-Board Arrays Procedure: 1.Stack the boards side-by-side by plugging JP1 of one board into JP2 of another DC2023A board. 2.Ensure different slave address settings for each of the boards. The address of each board is set by the DIP switch JP3 on the backside of the board. The setting must be unique for each board in the array. 3.Plug in the +12V VIN power into one of the boards as shown in Figure 12. Only one +12V power source is allowed. 4.The USB to I2C/SMBus/PMBus Controller may be plugged into any board. If no LTM2987s show up in the GUI, click the hourglass icon to enumerate the I2C bus and find the addresses of the parts. Go to step 2 to ensure that each board has a unique DIP switch setting. 5.Since the individual CONTROL lines are connected across the boards (CTRL is a common signal across all boards in the array), make sure that all CONTROL switches are set to the RUN position. 6.Relaunch LTpowerPlay. It will enumerate the entire board array and build a representative system tree and read all hardware settings into the GUI. Attention: Once the GUI has launched, click the “RAM->NVM” button in the toolbar to ensure that the slave addresses are retained after a power off or reset. Otherwise you may lose communication with the slaves after a power cycle or reset event. Figure 12. Array of Multiple DC2023A Demo Boards dc2023afa 13 DEMO MANUAL DC2023A Setup Procedure for Multi-Board Arrays Ensuring Slave Addresses Do Not Conflict There is a small DIP switch on the backside of the DC2023A. It is used to set the slave address of an I/O expander which provides for the addition of multiple boards to a setup. Figure 13. DIP Switch Set to All Zeros (0x20) The I/O expander has a base address of 0x20. The DIP switch settings set the offset. The three switches that may be changed are labeled A0, A1, A2. Examples below set the boards to addresses 0x20 and 0x27. Figure 14. DIP Switch Set to All Ones (0x27) dc2023afa 14 DEMO MANUAL DC2023A DC2023 Details—top Table 1.
