First question asked Welcome!

Hi,

We need an isolated gate driver which can also do 100% duty cycle.

Do you have parts?

I assume the "coreless technology" gate drivers can not do 100% duty?

We actually are just using the LTC7860 surge buck converter, but need to use it with an NFET instead...hence we need to isolate the gate drive to the NFET.

Dear @cupoftea ,

In our portfolio we don't have any dedicated gate driver for 100% duty cycle/ 0 Hz frequency operation, 

You can try this 0Hz operation by adding a charge pump circuit and a timer-based circuit to the gate driver.

You can explore our Gate driver portfolio in the link- https://www.infineon.com/cms/en/product/power/gate-driver-ics/#!products
