I am adapting the TPS23756EVM design to a non-PoE, 12V-only application. The high-voltage capability of this design reduces the need for surge protection in automotive power applications, which can reach 80V.
I would like a sanity check on connections for the following pins:
Vss - Tie to RTN, since Hot Swap is not needed
DEN - leave open? Don't need PoE signature
PPD - tie to Vss
CLS - leave open? Classification not used
APD - tie to ARTN or through Zener-protected resistor to Vdd?
The remaining pins would be connected as they are in the EVM.
