DESCRIPTION

LTC2977 8-Channel Power System Manager

with EEPROM

The DC1540B is a demonstration system for the LTC®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 (USB to I2C/SMBus/PMBus Controller).

DEMO MANUAL DC1540B

QUICK START PROCEDUREThe 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 PROCEDURE8. 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.

7dc1540bf

DEMO MANUAL DC1540B

QUICK START PROCEDUREThe 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.

14dc1540bf

DEMO MANUAL DC1540B

DC1361B – ADJUSTING THE MARGIN/TRIM RANGE AND RESOLUTION OF THE OUTPUT VOLTAGESThe 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.

DEMO MANUAL DC1540B

MEASURING CURRENTIt 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.

DEMO MANUAL DC1540B

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.
