Follow-up of Using IR21531 as a simple 1 channel gate driver

After doing the above question (I'm very sorry, beacuse my question seems a XY one), I'll try to explain better what I believe that I want (current circuit below):

I'm doing a space-saving design for a LED driver. On it, I only have a 200V PSU and a 3.3V PSU.

The module drive with PWM a LED strip, but the control signal will be of 3.3V and the MOSFET needs more than 10V to trigger. How can I get let's say 15V for driving the gate?

I've seen some vague words on some electronics forums saying that I could use a zener diode. How could I use the zener diode?

I'm open to suggestions. Also I could use a optoisolated transistor along with the zener.
