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…
Hi Elliot! I'm very excited that we're getting output! First, after reading into this a bit more it might actually be better for you to use the UCC2813-2 instead of the UCC2813-3. This device has a wider gap between the UVLO on/off threshold and that…

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…
Part Number: UCC2813-3 Other Parts Discussed in Thread: UCC2813-2 , , UCC2813-0 , UCC2813-1 , UCC2813-4 , UCC2813-5 Hi Team,
UC2813-x can work with switching frequency up to 1MHz. But in datasheet 7.5 Electrical Characteristics: Oscillator session.…
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?

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.
Flyback output is isolated and the positive node can be connected to GND. In this case the negative node is the negative voltage. Any PWM controller can cotrol flyback application. Example UCC2813-3 or any of this family.
Andreas,
TI general purpose, current mode PWM controllers can be set up for VMC by feeding the RAMP into the CS pin and they are not topology specific so they can be used for flyback, forward, buck, boost, etc. Configuring a CMC for VMC is a feature…
