10.5
During output short circuit, the FB voltage > 4.8V. The SOFTS pin start to charge from 4.4V to 5.4V. When it
hits 5.4V, the controller enters auto-restart mode. The blanking time is around 34ms.

When Vcc is greater than 17V while Vsofts is less than 4V during start up, the controller enter Vcc overvoltage
protection, i.e. auto-restart.
