The TPS53353 module works well when the output voltage is 1.2V, where R19 equals 10k ohm, and R78 equals 20 ohm.
But when we adjust the R19 and R78 to 49.9K and 24K, the output voltage is zero.
And we also adjust the discrete component as WEBNCH, but still no work.
Questions:
1. Is there any component selection is incorrect?
2. VFB equals to 0.6V typically as described in datasheet, and the output voltage WEBENCH is 0.6V*(61.9K + 10K)/10K = 4.3V, not the desired 5V output.
