In TPS63020 datasheet the sample schematic show that the EN pin #12 is connected to GND through the capacitor C3.
Then in the WEBENCH Power Designer also displays the same schematic as in the datasheet. (i.e) EN pin #12 is connected to the GND through the capacitor C3.
In the same datasheet at page #4 in pin functions table, it is stated that the EN pin #12 should be kept high to perform the operation of the IC. This is also explained in page #9 section 7.3.3 (Device Enable)
In the user guide “TPS63020EVM-487” , the EN pin #12 is kept high by connecting it to VIN.
Kindly clarify the simplified schematic in the datasheet of TPS63020.
