Part Number: UCC28742 Hello TI Experts,
I am working on a high-voltage flyback SMPS design using the UCC28742 with optocoupler feedback for an inline air purification system.
The design has been implemented based on:
TI datasheet recommendations…
Part Number: UCC28742 Other Parts Discussed in Thread: TIDA-01505 , UCC28C43 , UCC28722 Tool/software: Hi team,
Can the UCC28742 IC operate in quasi-resonant mode? If so, why does it not have a QR input?
Regards,

Part Number: UCC28742 Hii Team,
I want to simulate UCC28742 IC in any of the open source simulation tools. Can you please suggest me any simulation tool for this ?
Regards,

Part Number: UCC28742 Tool/software: Hi Team ,
I m using your UCC28742 Simplis model for simulation but we are getting errors while simulation it .Below is the error message i m getting .i just want to know weather we can run this example simulation…
Part Number: UCC28742 This is a general question regarding design of flyback converters.
In a flyback converter design, the transformer datasheet specifies both the turns ratio (with tolerance) and the primary and secondary inductances (also with tolerances…
Part Number: UCC28742 Tool/software: Hi,
Thank you for your reply. Attached is circuit of output part, now the output capacitance is about 700uF. It maybe a little small, but I think is OK. And I try increasing the capacitance, it seems almost the same…
Part Number: UCC28742 Tool/software: Hi,
When I use UCC28742 to ouput 5.2V(main feedback), 15V and 24V, 5.2V has overshoot. Maximum voltage is about 5.8V, exceed 10%. At the beginning, switching frequency is high, how should I adjust the parements?…
Part Number: UCC28742 Hi,
I have used your WEBENCH power supply designer to design a 480VAC to 700VDC then 28V 4A DC. But when I Using TIna to simulate it not getting 28V at the output. plus, I cannot find the model for UCC24636DBV. I need your help…
Part Number: UCC28742 Other Parts Discussed in Thread: UCC24636 Hi!
I have used you online WEBENCH to simulated a 100V - 700VDC input and 28V output flyback. The shcematics is attached. I also attached a DC-Link from 3 phase 480VAC to 700VDC rectifiy…
