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 Hi,
Can you please suggest IC that is cheap(very low cost) and complete power supply design should also very low cost and
can be used for
Input 85 to 265V AC
Output 5V and 1A/2A/3A supports.

Part Number: UCC28742 Other Parts Discussed in Thread: PMP11371 , UCC28740 Hello,
I am considering a circuit with the following specifications. I performed calculations using WEBENCH, but the efficiency is around 81%. Is there a reference design available…
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?…
