Typical output current capability vs fsw

jvl

Hi,

On CAB400M12XM3 datasheet, at the end, the Typical output current capability vs fsw figure is shown for an inverter application.

I get that this is only possible in the depicted conditions (Tc, Vds, Tj, Rg and MF).

How this relationship is obtained? Can I guess so?

• Psw (Ptot, Pcond, Etot(Vds), fsw)
• Ptot(Tj, Tc, Rthjc)
• Pcond(Ids, Rdson)
• Rdson(Ids, Tj)

I tried to emulate the curve but no success with this "algorithm".

What Ids is considered for a particular Iout with MF=1?
