When the EN is high, the device starts switching and the discharge is off for both devices. The differences in soft start, ovp, and ocp are outlined in the table when enabled.

Hello,

Could use TPS535A to replace the TPS535 directly? any risk?

The TPS53515A and TPS53515 are the same device except for the trim option changes shown here in Link.

If the ovp, ocp response difference is acceptable and the difference soft start time acceptable, i do not see a risk
