Tool/software:
Hi Team,
My customer have a question of TPS54360BDDAR, below is their schematic:
The range of input voltage is from 12V to 48V, and the Iout is below 3A.
The two chips in the picture have two output voltage, respectively: 5V and 3.3V. The 3.3V output waveform is as below:
Below is the waveform of SW pin:
The other chip with 5V output that waveform is:
the waveform is unstable and fluctuate from 4V to 6V.
In addition, the voltage of FB pin is 0.8V that is normal.
Could you solve this problem?
BR,
Moon
