Hi expert team
Customer is using TPS40428 with CSD95378, the VIN is 12V. We encountered some abnormal issue: when they set VOUT=5V via FB resistor, the duty cycle will be nearly 100%. But if we adjust the VOUT via PMBus, the circuit can output 5V. Can tps40428+CSD95378 support 5V output? Or do you have any insights about this issue? Thanks!
