We seen the IFX DS of SIC MOSFET have different Vgs spec from different package.
1. can you help us to confirm that following spec? thanks!
Vgs.dynamic -5 to +23V@tpulse,negative<15ns, why only negative pulse time in DS?
Vgs.recommended 0 to +18V
Vgs.dynamic -7 to +25V@tpulse,positive<1% duty cycle / fs, why only positive pulse time in DS?
Vgs.recommended -2 to +20V, why recommended Vgs use -2V for MOSFET turn off ?
2. Last question is whether Infineon SIC MOSFET has been changed from trench to planar structure?
I am trying to tune the cascaded PI controller for 3.3kW PFC. The cascaded PI controller has outer voltage Loop and a inner current loop. How should I approach to choose the correct Kp , Ki values for both Loops for different load current and for Input RMS voltage of 200 to 250v.

您好，我最近在设计一个3KW 400V/54V DCDC LLC，想寻求一些高功率密度和高效率的设计。我在英飞凌的文档中看到了 750W 400KHZ LLC 380V TO 12V 的效率非常高的设计。不，请提供一些参数，非常感谢
L5 in the dimensional drawing indicates the length of which part of the lead?
I think it is long up to the bulge of the lead.
The dimension L5 > L1-L is also listed as "lead dimension uncontrolled in L5".
