Can we use 3.3 to 5 voltage logic level converter to drive a sensor?
You probably could, since sensors normally don't take much current, but where would 5V for the translator come from? The translator has usually two power inputs, for the 3.3V side and for the 5V side, and you power them somehow with 3.3V and 5V respectively.

There is plenty of boost converters, discrete and modules, isolated and not isolated. For all sorts of current. It would be easier to guide you with more data about what you are doing.
