LM5030: LM5030 transformer parameters

Part Number: LM5030
Other Parts Discussed in Thread: TIDA-01352

Dear mr.

My questions:

1. I try to build power supply 400W, Vin=18V-29V to 300V with LM5030 and order for it planar transformer with next parameters:  500W, n=1:19,  Lprimary1-3= 8.5uH (10kHz)

I can't got more than 120W even PWM close to 50%. Do you see any problem with parameters of the my transformer?

2.I would compare with transformer from the TIDA-01352, but Into the manual for TIDA-01352 page 14  I see

<The design uses push-pull transformer (part number 750343547) from Wurth Elektronik.

But I can't find specification ( inductance and resistance of primary ) on the Wurth Elektronik internet side (it seems to old information)

Do you have spec of the 750343547 transformer.

Regards.

Mic.
