Hello PI,

               I am using InnoSwitch3 Pro Inn3370C for Power supply design, we are facing different issues like,

1. Facing issues to restart the system again, it's started (there is 5V at VBus) but not going Configured 
2. As per the configuration Vout not going to change (Inno3Pro_ramp) it's remains same 5V
3. If configure Vout as 8V, device get restart 

It's work at 1st start (configured and take load upto 5A) after that when I try restart it again within a min after Vbus 0V, it's not taking configuration parameter or Q4 not goin to enable but there is voltage 5V at Vbus
   No change in voltage after configuration which I set 8v in configuration, it's remains 5v at Inno3Pro_Ramp code which is need to increase linearly as per the code.

Please check schematic design and revert back asap
