Quick Start Procedure

How to Operate in Non-SPI Mode
The EVAL-LT8277-AZ is easy to set up to evaluate the performance of the LT8277. Follow the steps below:
1. With the power off, connect the load between the V
keep the circuit shut down. With the power off, connect the input power supply to the PV
sure that the input voltage does not exceed 36V.
2. Set JP1 to NO SYNC/SSFM or SSFM position.
3. Set JP3 to 60V or 36V.
4. Turn the input power supply on and make sure the voltage is between 9V and 36V to start the operation.
5. Release the connection between ENABLE and GND.
6. Observe the output voltage at 60V or 36V, depending on JP3 selection, with an output current ranging from 0A to 3A.
How to Operate in SPI Mode
1. Follow the EVAL-LT8277-AZ GUI manual to download, install, and setup the SPI GUI interface.
2. With the power off, connect the load between the V
keep the circuit shut down. With power off, connect the input power supply to the PV
the input voltage does not exceed 36V.
3. Set JP1 to the "NO SYNC/SSFM" or "SSFM" position.
4. Set JP3 to the "EXT_CTRL" position to enable GUI control of the MODE pin.
5. Connect a ribbon cable (CA2440) between the J5 communication connection and a Linduino One (DC2026C) demo
circuit.
6. Connect a USB cable between a PC and the DC2026C.
7. Start the GUI program.
8. Turn the input power supply on between the PV
36V to start operation.
9. Release the connection between ENABLE and GND.
10. Use the GUI to evaluate the performance of the EVAL-LT8277-AZ.
