Part Number: UCC28730-Q1 Other Parts Discussed in Thread: UCC28730 Hello,
We have a concern about creepage at UCC28730-Q1 device.
We have detected that in our design, we will have up to 510Vrms between HV pin and DRV pin.
We need to ensure that the creepage…
Part Number: UCC28730-Q1 Other Parts Discussed in Thread: UCC28730 How do we implement loop compensation in UCC28730 as well as other such Light load efficient flyback controller?
There's no COMP pin available.
Part Number: UCC28730-Q1 Other Parts Discussed in Thread: UCC28730 Hello,
Regarding the controller UCC28730-Q1, I have another 2 concerns:

Part Number: UCC28730-Q1 Hi,
I saw that this component is limited to 700V (HV in). Currently, we are using it for a 400V system, but if we use it in an 800V system can we place some limiting resistor in the HV input to limit the voltage to limit the voltag…
Hi Mr. Ciril,
It's hard to tell what is going on with the waveforms shown.
1. Please probe the transformer aux winding properly with correctly polarity. Most probably it could be shutting down due to OVP.
2. 240khz suggest the system is unstable.…
Hi Dhaval,
Thank you for reaching out.
1. There is only a slight difference. For example Rvs1 is 58k as per the formula in datasheet. Whereas the one in excel sheet optimizes based on available resistor values. It is there in a sheet titled "LOOKUP TABLES…
Part Number: UCC28730-Q1 Other Parts Discussed in Thread: UCC28730 Hello, How do I go about obtaining an unencrypted version of the UCC28730 spice model so I can import it to LTSpice? Appreciate the help!
Part Number: UCC28730
Hello,
Where can i found the Spice model of :
UCC28730 and UCC24650
i need the spice model in order to simulate a circuit on Altium, there is only the encrypted version.
Thanks
