TINA/Spice/LP55231: need for the spice model or at least some level of modeling for this LED driver

Tool/software: TINA-TI or Spice Models

Hi all,

I'm trying to establish what size my capacitors on the input and output of the LP55231(LED driver) should be to minimize sulficiently voltage ripple. for that I would need to get the spice model for the chip. I tried to find it on the product page as well as on WEBBENCH to no avail. I understand it's a complex chip and maybe not all behavior is easily modeled. But really, I'm talking about turning an LED on/off here, nothing too fancy. So I was wondering how to go about getting a model, or an approaching model.

Any idea?

Thanks for your help!
