IRS27951 / IRS27952

Hi Guys!

I hope some of you heard about IRS27951 or IRS27952 from IRF. These are 8pin half-bridge resonant controller ICs, they have a lot of improvements from the common-known IR2153 series.
- progammable dead-time
- increased FET-driving current
- easier variable frequency controll
- over-current sense with FET's Rdson
Due to its highly-integrated, with very few external components a stabilized-output high efficiency SMPS could be built from few hundred watts, up to 1kW.
The problem is that they are really new, and I haven't seen them anywhere (farnell, digikey, tme).
Anybody seen this IC somewhere?
I would really get my hands on few peaces.
