It would help (some of us anyway :-) ) if you specified eg Vin, Iin, Vout,
Rl
on each post where these are relevant. We can go back and garner same on
each post.
Ton toff also useful - was 5 uS/2 uS but may change.

We/I may not remember eg the load value from post to post. Some may and it
MAY be the same as N posts ago. Or not.

If Rl is 6R8 still then Pout is now about 2.5W.

My above calcns at 70 uH, 9V, 5 uS on suggested that power in would be
about 2.9W.
IF so then you now have about 2.5/2.9 efficiency =3D~ 86%. Sounds good.
What you measure for Iin I know not andI assume Vin =3D 9V but ... . .

In this case Vin is V at FET source (and probably max +ve Vgate but than
can be higher +ve if you wish).
Vgs must fall to about 0V differential whejn the FET is meant to be off.
