DESCRIPTION
LTC2977 8-Channel
Power System Manager
with EEPROM
The DC1540B is a demonstration system for the LT C
®
2977
8-channel I2C/SMBus/PMBus Power System Manager
with EEPROM. It consists of 2 circuit boards namely the
DC1360B and DC1361B. The DC1360B contains all the
circuitry needed to insert the LTC2977 into a power system
and control eight power supplies. The DC1361B contains
eight power supplies (LTM4603EV) which are configured
to be controlled by an LTC2977. Together these two boards
form a sophisticated, 8-channel, digitally programmable
power supply.
This demonstration system is supported by LTpowerPlay™
software and a graphical user interface (GUI) that enables
complete control of all the LTC2977 features. You can obtain
this GUI from the website www.linear.com/ltpowerplay.
com. LTpowerPlay and the DC1540B, create a powerful
development environment in which you can design config-
uration settings for the LTC2977. The configuration settings
can be stored in the LTC2977 EEPROM and also in a file,
which can be used to order pre-programmed devices.
LTpowerPlay displays all of the configuration settings and
real-time measurements that the LTC2977 performs and
allows easy access to the fault log created by the LTC2977.
The LTC2977 on the DC1360B comes pre-programmed with
EEPROM values appropriate for the eight power supplies
used on the DC1361B.
The LTC2977 can be configured to monitor current
on odd numbered channels. In the DC1540B, this
feature can be enabled on Channel 7 (see “Measur-
ing Current”). Channels 1 and 2 can be configured
to do coincident tracking of Channel 0 by using JP2
and JP3 (see “DC1361B Details – Top Side”). An LTC
Hot Swap™ circuit on the DC1361B enables the LTC2977 to
soft-start VIN and shut off VIN in response to output faults.
Multiple DC1540Bs can be cascaded together to form
a high channel count power supply (see “Multi-Board
Arrays”). This configuration demonstrates features of the
LTC2977 which allow timing and fault information to be

shared across multiple LTC2977s, allowing the formation
of a single, coherent power supply control system. This
configuration is easily supported by the LTpowerPlay
GUI and allows the user to configure up to 9 LTC2977s,
controlling up to 72 separate power supplies.
To get this demo system up and running, connect the
DC1540B to your computer using a DC1427A or a DC1613

QUICK START PROCEDURE
The following procedure describes how to set up one DC1540B.
1. Remove both boards from bag.
2. Place boards on level surface. Connect boards together using the 54-pin edge connector. See below.
Figure 2. Plug Boards Together
3. On DC1360B, set jumpers and switches as follows. See also Table 3.
a. Set both SW1 and SW2 (CONTROL0 and CONTROL1) to GND.
b. Set JP5 to OFF.
c. Make sure JP6 is installed.
d. Set JP3 (ASEL0) to LO and JP2 (ASEL1) to LO.
e. Set JP4 to ON.
4. On DC1361B, set jumpers and switches as follows. See also Table 3.
a. JP1 = INSTALLED
b. JP2, JP3 = SOFT START
c. SW1 = MASTER
5. Plug in the USB to I2C/SMBus/PMBus Controller into a USB port on your PC.
6. Connect a 12V power supply with >1/2 Amp capacity to the VIN+ and VIN– inputs of the green terminal block J11
on DC1361B. Do not turn on 12V yet. Be careful to hook up polarity correctly! See Figure 5.
7. If you have a DC1427A, connect to J4 on DC1360B as shown in Figure 3.

QUICK START PROCEDURE
8. Launch the LTpowerPlay GUI.
a. The GUI should identify the LTC2977. The system tree on the left hand side should look like:
b. Confirm that the LTC2977 is communicating. A green message box shows for a few seconds in the lower left
hand corner
c. In the Toolbar, click the “R” icon to read the RAM from the LTC2977. This reads the default configuration from
the RAM in the LTC2977 on the DC1360B and loads it into the GUI.
d. Save the demo board default configuration to a (*.proj) file. Click the “Save” icon and save the file. You can
chose your own filename.
9. Turn on the +12V power supply.
10. Slide the 2 black switches CONTROL 0 and CONTROL 1 to the HI position. This turns on the board.
7
dc1540bf
DEMO MANUAL DC1540B
QUICK START PROCEDURE
The System Tree on the left hand side should turn all green. All 8 green LEDs on the DC1361B should illuminate.
11. You are now ready to execute one of the LTC2977 demos embedded in the GUI or experiment with the part.
LOADING A 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 arrow. This loads the file into the working RAM of the LTC2977.
3. To store in EEPROM, click on the STORE button. It is the icon with the “W” on it (see below).
NOTES:
1. To configure the jumpers and switches, see Tables 3, 4, 5 and 6. If using more than one LTC2977, use the ASELs
to assign different addresses for each LTC2977.
2. On DC1361B, set the MASTER/SLAVE switch to MASTER if you want the Hot Swap chip to shut off in response to
an output OV fault. To recover from shut off, you must command the channel that produced the OV off then on
with the OPERATION command or you can toggle the VinShareEnable bit in MFR_CONFIG_ALL_LTC2977 to 0 then 1.
3. When the USB to I2C/SMBus/PMBus controller power is applied, the LTC2977 will load the contents of its EEPROM
into operating RAM.
4. For help on any command, highlight the command in the GUI and press F1.
5. The LTM4603 outputs may be shorted indefinitely. This is a good way to induce UV faults.
6. If the DC1360B is used without the DC1361B, it will report an overtemperature fault because its VSENSE inputs
are floating. This may be avoided by tying the VSENSE inputs to defined voltages.

Setting the Device Address
The LTC2977 can be configured to respond to one of 9
addresses for a given MFR_I2C_BASE_ADDRESS value (the
factory default value base address is 7’h5C). In addition,
the LTC2977 will always respond to its global address and

DC1361B - CHANGING THE NOMINAL OUTPUT VOLTAGES
The Nominal VOUT of any channel on the DC1361B can be
changed by changing the RSET resistor from VFB to SGND.
These are: R21, R26, R29, R38, R48, R67, R73, R79. See
Figure 9. The value for the RSET resistor is:
RSET = 60.4k/((VOUT/0.6) –1))
See also the LTM4603 datasheet Table 2. VOUT0 may be
adjusted up to 5V. The other channels may be adjusted
up to 4V.

DC1361B – ADJUSTING THE MARGIN/TRIM RANGE AND RESOLUTION
OF THE OUTPUT VOLTAGES
The resolution and range can be adjusted for any output
on the DC1361B by simply replacing the below resistors.
Use the LTC2977 Resistor Selection Tool (spreadsheet) for
calculating resistors values and proper DAC range settings.
The design tool refers to R20. This is the upper divider
resistor which is 60.4kΩ inside the LTM4603.
The design tool refers to R10. This is the lower divider
resistor which is RSET (See Figure 9).
The design tool refers to R30. This is the margin/trim
adjustment resistor.
On the DC1361B, the lower divider resistors (R10) are =
RSET for each channel = R21, R26, R29, R38, R48, R67,
R73, R79.
On the DC1361B, the adjustment resistors (R30) are =
R55, R56, R57, R58, R59, R68, R74 and R80.

MEASURING CURRENT
It is possible to measure the current on Channel 6 by using
Channel 7 in “Hi Res” mode. Follow the instructions on
pp.9 and 10 of DC1361B schematic. Remove R88, R89
and move them to R86, R87. Also remove the preload
resistor R75 (top side) on DC1361B schematic p.9 to
measure only the current going out of the board.
One simple checkbox in the GUI sets up Channel 7 to mea-
sure current. In the MFR_CONFIG_LTC2977 register check
the box that says “adc_hires”. Apply a load between the
big turrets 1.0V and GND on VOUT_6 and read the voltage
across the 10mΩ current sense resistor by viewing the
READ_VOUT register on Channel 7 in the GUI.

FAULT ZONE CONFIGURATION AND FAULT PROPAGATION
The LTC2977 has four FAULTB pins within two fault zones.
Each channel can pull FAULTB pins within its zone low.
Also, any channel can shutdown in response to FAULTB
pins within its zone, therefore, dependencies between any
channel(s) can be established. See Applications section
of the datasheet. See Figure below. Zone 0 and 1 are tied
together on the DC1360B through R9. Therefore, any
channel can shut off in response to any other channel
on the LTC2977. Additionally, each FAULTBz pin ties to a
FAULTn (n =1,2,3,4) line on the DC1360B which is bussed
Figure 13. Fault Zones and Fault Pins on DC1360B
to other DC1360B’s in a multiboard array. Therefore, it is
possible for any channel in an array to shutoff in response
to any other channel.
FAULTn lines are on p.2 DC1360B schematic J2, J3.
To disconnect Fault zone 0 from Fault zone 1, remove R9
on DC1360B.
