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 I
2
C/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 V
SENSE
inputs
are floating. This may be avoided by tying the V
SENSE
inputs to defined voltages.
