Loop compensation design
Posted by: Dev0509

I am facing an issue in calculating the feedback loop compensation for TNY268. Do you have literature that could help in the calculation?
What is the internal pullup resistor value at EN/UV pin?

Hi,
Can we get the Spice file of ICs to Simulate the SMPS power supply?
It would be help us to understand the working of ICs other then PI Expert and PIxls.
Hi,
Unfortunately, spice files of the ICs are unavailable.

Hi,
Thank you for considering Power Integrations for your solution.
Since the TNYSwitch II family has simple ON-OFF control, no loop compensation is required. Only a 100nF cap is required from the voltage divider network of the output to the TL431.
Please refer to DERs for more details:
