Hi Harish,
Thanks for your response.
Now my project is working well. The only difficulty is to start up the power supply with a low input voltage equal to 60 V. Moreover, the output voltage tends to oscilate when I turn-off the load. Apart from that, the…
Part Number: UCC28700-Q1 Other Parts Discussed in Thread: UCC28700
The question I have regarding UCC28700 flyback controller is what is the TI recommended way to shutdown the controller UCC28700, when input dc VBLK goes below a certain level.
We can…
Hi Harish,
i'm just trying to verify this idea with UCC28700 Tina-TI model from TI website. However I got the error "convergence problem".
Maybe you can shoot what is the trouble? Attached is my simulation file.
Thanks! UCC28700 high side…
Part Number: UCC28700-Q1 Other Parts Discussed in Thread: UCC28700 , UCC28600 The simulation model for UCC28700 doesn't have a transformer model included. How to properly model a flyback transformer with an auxiliary winding.
Thanks

Part Number: UCC28700-Q1 Other Parts Discussed in Thread: UCC28700 I hope someone can help me get an non-encrypted spice model for the device.
Thanks in advance
Part Number: UCC28700-Q1 Other Parts Discussed in Thread: UCC28700 Hi team,
The PSpice Model of UCC28700 cannot be opened using LT Spice. An error like this will be displayed after opening.
But I can open PSpice Model of other products.
So can you provide…
Part Number: UCC28700-Q1 Other Parts Discussed in Thread: UCC28700 Hi,
I need to simulate the performance of the part number UCC28700-Q1. I'm unable to simulate this part number because only encrypted SPICE models are available on TI's website. Please…
Part Number: UCC28700-Q1 Other Parts Discussed in Thread: UCC28700 hi experts
i saw VVDD(on) and VVDD(off) parameters in UCC28700 datasheet. it seem like these parameters are related with UVLO function.
so how to understand these two parameters?
does VDD…
Part Number: UCC28700 Hi
The datasheet of the UCC28700 specifically states that there should not be a filter cap placed on the voltage divider on the VS pin input. But if we look at Figure 29 (or search for "C6" in the datasheet) we see that one is added…
