DC2198A - Demo Manual

DEMO MANUAL DC2198A
16-Channel Power Supply
System Featuring the LTC2980
Power System Manager
DESCRIPTION
The DC2198A is a demonstration system for the LTC®2980
16-channel I2C/SMBus/PMBus power system manager with EEPROM. The LTC2980 monitors and controls
16 power supply rails. The DC2198A demonstrates the
ability of the LTC2980 to sequence, trim, margin, supervise,
monitor, and log faults for sixteen power supply rails. Each
power supply channel’s output voltage is monitored and
the LTC2980 monitors its own internal die temperature.
The DC2198A is a single circuit board that contains sixteen
independent power supply rails. The board employs sixteen
LTC3405A 300mA switch-mode regulators, which are
configured to be controlled by the LTC2980. The LTC2980
is available in a BGA 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 LTC2980. Together, the LTpowerPlay
software and DC2198A hardware system create a powerful
development environment for designing and testing LTC2980
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 LTC2980. Telemetry allows easy access and decoding
of the fault log created by the LTC2980. The board comes
pre-programmed with the EEPROM values appropriate for
the sixteen power supplies used on the DC2198A. Just plug
and play!
Multiple DC2198A boards can be cascaded together to
form a high channel count power supply (see MultiBoard Arrays). This cascaded configuration demonstrates features of the LTC2980 which enable timing
and fault information to be shared across multiple ICs.
The user can configure up to four DC2198A boards,
thereby controlling up to 64 separate power supply
rails. Larger arrays of LTC2980s are supported through
programmable I2C base address or bus segmentation.
The DC2198A 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 following is a checklist

DEMO MANUAL DC2198A
QUICK START PROCEDURE
The following procedure describes how to set up a DC2198A
demo system.
1. Download and install the LTpowerPlay GUI:
www.linear.com/ltpowerplay
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 DC2198A board using
the 12-pin ribbon cable.
6. Launch the LTpowerPlay GUI.
a. The GUI automatically identifies the DC2198A and
builds a system tree. The system tree on the left
hand side should look like this:
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 DC2198A.
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 -> NVM”
icon in the toolbar.

b. A green message box will be displayed for a few
seconds in the lower left hand corner confirming
that the DC2198A is communicating:
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.
Loading a DC2198A Configuration (*.proj) File with the GUI
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 LTC2980.
3. To store the configuration to NVM (EEPROM), click on
the “RAM -> NVM” icon.
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.

COMMON DEMO BOARD OPERATIONS
MARGIN ALL RAILS
The LTC2980 power system manager not only monitors
each of the sixteen outputs but also 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.
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 setpoints to margin
high, margin low, and back to nominal voltages.
Each LTC2977 inside the LTC2980 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 LTC2977 data sheet
for complete ADC timing specifications.
Creating a Fault
There is a pushbutton on the DC2198A 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.
The LTC2980 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 DC2198A demo board has been configured
to sequence off all channels when a fault occurs. Pressing
the “CREATE FAULT” pushbutton causes the Fault pin to
6
dc2198af
DEMO MANUAL DC2198A
COMMON DEMO BOARD OPERATIONS
be asserted low which triggers all rails to power down
based on the TOFF_DELAY times.
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 DC2198A
A reset pushbutton is provided on the board. To reset all
devices on the DC2198A board and reload the EEPROM
contents into operating memory (RAM), press RESET
(SW2) on the DC2198A.
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.
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.
Figure 4. Sequencing Off (SeqOffOnFault = 1)
DC2198A LEDs
Each individual channel on DC2198A 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 LTC2980 is powered. The red LEDs will illuminate
when an alert or a fault has occurred.
Sequencing Output Channels
The LTC2980 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
Figure 5. Sequencing Off (SeqOffOnFault = 0)
dc2198af
7
DEMO MANUAL DC2198A
COMMON DEMO BOARD OPERATIONS
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 LTC2980, the TON_DELAY and TOFF_DELAY values
extend to 13.1 seconds, providing very long on and off
sequencing of power supply rails.

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.

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 (uptime, voltage, current, temperature)
that can be analyzed to help determine the cause of the
fault. It is a powerful diagnostic feature of the LTC2980
on the DC2198A 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 LTC2980 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.
10
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 -> 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.
dc2198af
DEMO MANUAL DC2198A
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).
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.
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
LTC2980 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.
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 LTC2980
channels will shut down all 16 channels, and a fault on
any LTC2980 channel will propagate to all channels on the
DC2198A demo board since the fault pins are tied together.
Note: All FAULT pins on the LTC2980 are tied together on
the DC2198A 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 bi-directional, meaning the device may
drive its fault pin low (output) or may respond to the fault
pin when another device drives it low (input). Because all
fault pins are wire OR’d on the DC2198A, this hardware
configuration allows one to program each device’s fault
settings on a channel-by-channel basis. By default, the
LTC2980 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
dc2198af
11
DEMO MANUAL DC2198A
ADVANCED DEMO BOARD OPERATIONS
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 DC2198A.
Figure 10. Fault Sharing Utility in LTpowerPlay GUI
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.

SETUP PROCEDURE FOR MULTI-BOARD ARRAYS
Multiple DC2198A boards can be combined to control
up to 64 independent power supplies. Four boards may
be cascaded. The number of boards is limited by an
I/O expander chip that has three address pins, allowing
8 different combinations. This setup demonstrates the
coordinated fault responses and accurate time base shared
across multiple LTC2980 devices.
Procedure:
1. Stack the boards side-by-side by plugging JP1 of one
board into JP2 of another DC2198A 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 devices show
up in the GUI, click the magnifying glass 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. Re-launch 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” icon 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.

Ensuring Slave Addresses Do Not Conflict
There is a small DIP switch on the backside of the DC2198A.
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.
