Hello,
We are using TPS65400 on our board to generate the required voltages for FPGA, ADC, DAC, etc. After using the board for a couple of days, the PMIC doesn't turn on, the output voltages of SW1-4 become zero, and the current on the Power Supply drops to zero. Any suggestion about the root cause of this issue is highly appreciated.
Sincerely,
Nasim.
