10.7
If Vfb is found greater than 4.8V, Vsofts starts to charge up from 4.4V to 5.4V. Once Vsofts reaches 5.4V, the
controller enters auto-restart mode.

10.8
When the loading step from 2.22A to 4A, the FB voltage will be larger than 4.8V. Then the SOFTS pin starts to
charge from 4.4V to 5.4V. When it reaches 5.4V, the controller enters auto-restart mode. The blanking window
( SOFTS pin charge up time from 4.4V to 5.4V ) is around 32ms.
