Are there any experiences with the BTN-9990?
Is this as bad as the IFX-007 according to switching losses starting at low pwm-frequencies?
Thanks

Hi there,
Short answer, unfortunately yes. Anything above 5KHz would overheat.

Oh, that’s astonishing, but sadly foreseeable.
BTW: did you do own tests?
Thanks,

Nothing astonishing, they just repackaged the silicon. Yes, and if you look at the datasheet you will see the specs are nearly identical, just a little better on the high end of the envelope but under normal conditions they behave exactly the same. Very disappointing.
I do like however the new package. Low, compact profile and easy to cool. Also, they improved the datasheet, more information and easier to design.
Cheers,
