For the UCC2813-0, UCC2813-2 & UCC2813-3, Dmax = 100%, for these versions OUT pin Fsw= Fosc.
For the UCC2813-1, UCC2813-4 & UCC2813-5, Dmax = 50%, implemented using an internal toggle flip-flop. So for these versions, Fsw = 0.5 * Fosc.…
I just got back in to see if there were any comments added and noticed that schematic I cut and pasted is not showing up. I'm trying again by converting the Webench output to a Word document.

UC2813 has the same pin configuration as the UC2842/3/4/5 family. there is a detailed section in the datasheet for finding the voltage feedback loop compensation. The section is 188.8.131.52, Voltage Feedback Compensation, on page 25 of the datasheet…
Other Parts Discussed in Thread: UCC2813-5 , UCC2813-0 Hi all Would you mind if we ask UCC2813-0 to UCC2813-5? Our customer would like to start or stop the PWM controller in response to input voltage. So, we consider that it is possible to make it using Reset…
Based on this rather limited set of requirements, the tentative answer is YES.
Can you please clarify if the input voltage Vin is AC or DC?
If it is DC, then yes the UCC28740 can readily support that spec since the HV input is rated…
It is difficult to tell if that bobbin is designed to accept an EFD core just by looking at it. The shape of the bobbin appears to fit an EFD core shape, but only a datasheet for the bobbin will verify if its dimensions are correct for…
Here are some part numbers that appeared when I searched for your requirements. I recommend starting to look at UCC28600-Q1.
Other Parts Discussed in Thread: UCC2813-1 Hi,
I have designed Multi-output flyback power supply by using UCC2813-1 PWM IC,
Input and output specifications are as follows
Switching frequency -200kHz
Other Parts Discussed in Thread: UCC2800 I am currently using UCC2800 for a 100 kHz 20, 5 output, flyback supply and a UCC2813 for a boost supply. I need to change the frequency to eliminate some EMI issues.
What controller part do you recommend for use…
Thank you for uncovering several typographical errors in the application section of our UCC2813-x datasheet. We will begin the process to correct these errors, but this may take many weeks due to internal procedures. Meanwhile, I’ll address…
