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 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 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 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: UCC28750-SIMPLIS Other Parts Discussed in Thread: UCC28742 Dear Sir
I have sluj001a running fine on simplis. But when i modify into 24V configuration:
Change S1 winding to 350m(91uH)
RPL1 to 75k, RPL2 to 8.8k
Rcs to 0.33ohm, R18…
Part Number: UCC28742 Tool/software: Hello,
I am trying to use the design calculator tool (SLUC652b). I have inputted my values and chosen a desired minimum valley voltage of 0V. This leads to a recommended input bulk capacitance of 13.7 uF. However…
Part Number: UCC28742 Other Parts Discussed in Thread: PMP31193 Tool/software: i'm implementing UCC28742 by reference of PMP31193 in a three phase 380VAC design.
the circuit diagram is shown as below, i found that the output of 24V is only around 6V…
Part Number: UCC28742UCC28742 Circuit Design with Excessive AUX Voltage:
The UCC28742 integrated circuit (IC) datasheet specifies that it can safely operate with a bias supply voltage (VDD) between 9V and 35V.
In your WeBench design, the AUX winding…
