Part Number:UCC27712

Hi. As already written in thread title I must drive MOSFET with 3kHz and sometimes turn it constantly on. In datasheet it is written that "However, when a dedicated bias supply is used, constant on or constant off conditions can be supported"

What do you recomend to implement  dedicated bias supply for UCC27712?

I read that I could use charge pump, but can you please advice how should I change the UCC27712 supply circuitry for this ?

Thanks in advance UCC27712
