LM53635-Q1: Buck converter BODE PLOT TINA TI

Muhammad Ikram Ullah

Part Number: LM53635-Q1

I am using LM53635-Q1 model to compare the values reflected by WEB bench , TINA TI and then comparing it with actual values which i will get in the LAB with hardware chip. I have to do efficiency analysis and check the loop compensation : Phase and Gain , Web bench give us phase and gain value easily but when downloading same model and implementing in TINA TI and running AC transfer characteristics i am getting error " operating point not found " .

Hi Muhammad,

Where did you find the TINA model? I do not see it in a product folder.

Hello Muhammad,

I could able to get the inputs from the Modelling team regarding your issue. Actually PSpice models only support transient simulations. We cannot run AC analysis using these models. In addition, the user can only export Startup transient simulations from WEBENCH.

Hope this helps!
