TPS54335A/ Compensation Components

Other Parts Discussed in Thread: TPS54335A, TPS54331, TPS54332

Hi,

Please let me know about TPS54335A compensation components.
Specific examples of using the following components are introduced in the data sheet P23.
◇L1 = 15 µH,C6 and C7 = 47 µF,ESR = 3 mΩ

Could you tell me the formula that can be used comp parts(ｔｙpeII) to TPS54335A?
May I use an expression of TPS54331/TPS54332?
My apologies in advance for the newbie question.

Best Regards,
Yusuke/Japan Disty

    I personally use and recommend pspice average model to derive compensation components.  the model is available here:

    You can use the procedure outlined in the datasheet.

    You can use simple formulas if you want such as those in the datasheet you referenced.  Make sure to use the appropriate parameters from TPS54335 datasheet though.   should caution you that those equations are general approximations.  You should definitely verify your results with bench measurements.  I find the pspice modeling to much more accurate.
