Part Number: UCC2813-3-Q1 Tool/software: WEBENCH Design Tools Greetings
I am using UCC2813-3-Q1 for a simple forward converter. I find that the soft-start is not working. The first output pulse appears as COMP pin is around 1V. But the duty cycle is…
Hi, sorry it's been a couple of weeks but I still haven't gotten around to this! It's high on the list though and I hope to get to it between holidays.
Other Parts Discussed in Thread: UCC2813-3 I am looking for the spice model of UCC2813QDR-3Q1. I was able to find the UCC2813 -0 spice model. However, the operation of the two are different and I could not find UCC2813- 3 spice model.

Part Number: UCC2803-Q1 Other Parts Discussed in Thread: UCC2813-3-Q1 Hello Team,
I just got RFQ about UCC2803-Q1 from customer.
However when I look over TI.com, I found the UCC2813-3-Q1 which is very similar device. I think UCC2813-3-Q1 is lower price…
Hi Kieran,
Thanks for your interest in UCC2813-3. 60-75Hz switching frequency is extremely low and would require very large magnetics. Why is it important to sync the switching frequency with a video camera in your application?
Best Regards,

UC2813-x can work with switching frequency up to 1MHz. But in datasheet 7.5 Electrical Characteristics: Oscillator session. The oscillator…
Part Number: UCC2813-4 Hi, I just designed a fly-back DC-DC converter with UCC2813-4. But it seems not work in high efficiency.
I checked the waveform and found that the duty cycle is only about 29%. At the same time, there's no current flow through the…
Hi
(1) For the minimum VCC voltage, you need to make the VCC above UVLO_on. For UCC2813-0, the UVLO_on is 7.2 V.
(2) Here are differences for different part number from UCC2813-0 to UCC2813-5. They have different turn on voltage of UVLO.
(3) The maximum…
Part Number: UCC2813-0-Q1 Hello,
I am planning to design a flyback converter with the following specifications:
Vin: 9-18V
Vout: 300-500V
Output power: 20-40W
Operating frequency: 100KHz
Please clear/provide suggestions for the following points:
