Gate drive transformer.....will it saturate?

[grizedale]

I wish to use the HM42-40002LF gate drive transformer in a two transistor flyback converter at 67KHz

...however, the datasheet doesnt state the V.us value.

I cannot understand how i am supposed to work out if it will saturate or not.

For my application, i require v.us of T(sw)*12 = 180.

(im only driving the top fet by transformer).

I am amazed at the complete lack of off-the-shelf parts for this purpose...surely high side pulse transformer drive is very common?

Do you know how to work out if it will saturate or not (from above datasheet)?

I believe these would saturate if used as is. These seems to be simple transformers and that too without any airgap in core. You would need to design proper RESET circuit if you plan to drive these with unidirectional pulse. I hope I am making sense here.
