TPS54320: Help find compensation because Webench is not offering

Part Number: TPS54320
Other Parts Discussed in Thread: TINA-TI

Hi!

My customer wants to use Webench to deisgn with TP54320

These are his parameters:

VIN 10.8-13.2V

Vout 3.3 and 5V 3% acurancy

Iout 1.5A for 5V rail and 2A for 3.3V rail

I have set frequency at 700kHz getting inductors 10uH for 5V power supply and 6.8uH for 3V3 power supply. Both designs are X7R only and so far I do have these two type used for input and output buffer. Inductors are from IHLP2525 series.

why I am not able to see the old menu and recompensate the circuit for example TPS54320?

 The customer also tried Power Stage designer, but needs help.

Kind regards,

Marion
