DEMO MANUAL DC2598A

QUICK START PROCEDURE

Figure 1. Test Procedure Setup Drawing For DC2598A

Demonstration circuit 2598A is easy to set up to evaluate

the performance of the LT8390A Follow the procedure

below:
1. With the input power supply off, connect the input

power supply and output load as shown in the test

setup drawing in Figure 1.

2. Connect the EN/UVLO terminal to GND.
3. Make sure that the SSFM jumper is in the correct posi-

tion – either with SSFM turned ON or OFF. Only place

the jumper in the SYNC position if an external SYNC

frequency source is connected to the SYNC pin.

4. Turn the input power supply on and make sure the

voltage is between 4V and 24V for proper steady state

operation.

5. Release the EN/UVLO-to-GND connection.
6. Observe the 12V output voltage, the load current mea-

surement via the ISMON pin voltage and the high effi-

ciency of this small converter.
