Hey, i wanted to know that does the tina spice startup model given on ti.com have a zener across the PWM controller ?

Because while performing the overcurrent protection simulations, I am not able to get proper results.

I hope to find an answer for this

Hi Jash,

There is no Clamp Zener at CS pin.

I can help check your simulation if you can share it.

Regards,

Teng

I am sharing with you the .TCS file. I am not able to perform CC analysis on it. My max current value is 20 amperes and regulated output is 12 volts for an input range of 75 volts -135 volts.

Hi Jash,

The cycle by cycle current limited works well in the simulation.

And may I know what is CC analysis, and I didn't find it in TINA?

Regards,

Teng

Hi Jash,

I haven’t heard back from you for quite sometime, I’m assuming you were able to resolve your issue. If not, just post a reply below (or create a new thread if the thread has locked due to time-out) – thanks.
