BQ25606: bq25606 at 18V Continuous input voltage?

Part Number: BQ25606

The data sheet says 13.5V max, with a 22V absolute limit. There is a note about the peak switching ringing on the switch node. Is that what limits operating voltage to 13.5V?

What if I run this at 18Vdc max input continuously?

Is there another standalone part with power path management and at least 1A charge current that has a higher continuous operating voltage?

    bq25606 built in internal input over voltage protection(OVP) with typical voltage at 14.3V. When input voltage is above the OVP threshold, the charger stops switching so SW will not see high switching voltages. The operation voltage range is up to 13.5V and non-operational  voltage is up to 22V at VBUS.
