Hello,
I'm looking for a high-side gate driver that can deal with a range of about 100 to 200 V and support 100% duty cycle. I cannot find an exact device, however, I guess UCC27712-Q1 is a close solution if a constant voltage is supplied to its high-side floating supply by such means as flyback converter.
Questions
- Is it OK not to use the low-side driver of the UCC27712-Q1?
- If yes, how should pins related to the low-side driver (LI and LO) be handled on PCB?
- Can a back-to-back MOSFET be used for the high-side driver?
Best regards,
