TPS54526PWPR - Pin 11 not connected in schematic generated from Webbench

Hi,

this is regarding the buck converter TPS54526PWPR. We are using the schematic generated by Web bench for input voltage of +12V and output of 1.2V / 5A. 

In this schematic, pin 11 (SW1) is not connected and pin 8 and 9 are not short to ground. But the schematic in the datasheet shows these pins connected.

Please clarify if the pin 11 is to be connected to pin 10 or can it be left open.

Thanks,

Elizabeth

    Webench only shows generic pin function names not duplicates or pin numbers (SW instead of SW1 and SW2, PGND instead of PGND1 and PGND2).  You need to connect both SW1 and SW2 together (pins 10 and 11) and connect both PGND1 and PGND2 together (pins 8 and 9).  I'll see if I can get this corrected.
