LTM4622 INTVCC functionality

i want my board to support a wider range of voltages instead of 3.6 to 20, i want it to support 3.3 to 20.


i understood that for 3.3 input voltage INTVCC need to be tied to VIN. the problem is when VIN is greater then 3.3.


i wondered if i would tie the INTVCC to VIN via a resistor and tie INTVCC to GND with a zener diode to protect the pin from voltages above 3.3 is it possible?


attached a circuit for example.
