The TPS92075 datasheet COFF max rating is shown as 6V. During normal operation, the COFF is charged to 1.2V and pulled down. The application circuit in the datasheet and the EVAL(SLVU813) board shows a direct R-C from Vcc to COFF, but Vcc is specified upto 22V, typical 11V. I am concerned on startup and any other situations. Could COFF exceed the max voltage rating (or is there some max injection current spec)? Do I need to have a zener clamp on COFF?
