Hi,

There is a Tina model available for UCC28180:www.ti.com/.../toolssoftware.
At this time, there is only a simplis model available for UCC24612 and UCC256304.

dear Ben Lough,
I have download UCC25630X simplis model, but it is not the model with postfix .lb, it is simplis schematic with postfix .sxsch. So would you like to help us to solve this problem? thanks!

Hi,

I will look into this issue. Also I forgot to mention that a webench model is available for UCC256304 which might be of use to you:webench.ti.com/.../quickview.jsp

Hi,
when opening UCC256303_simplis_trans.sxsch, it notes that the model is encrypted.
So would you give me some suggestion how ti obtain unencrypted simplis model for the IC.
thanks so much.

Hi,

I'm not able to provide decrypted models. What is it you are trying to simulate?

Hi Xinhong,

RVCC of UCC256304 is 12V typical. The UVLO threshold of UCC28180 is 12.1V maximum. It would be better to power UCC28180 from the VCC rail of UCC256304 and use a small LDO to regulate.

Ben Lough
