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 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…
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…
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. The oscillator…
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?
Part Number: UCC2813-0-Q1 Hello,
I am planning to design a flyback converter with the following specifications:
Output power: 20-40W
Operating frequency: 100KHz
Please clear/provide suggestions for the following points:
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 detailed…
Part Number: UCC2813-0 Other Parts Discussed in Thread: UCC28740 HI sir
I want to design a AC-DC power that Spec is AC 200V~AC500V (3 phase power system)
output need isolator 3.3v/3A
ON semi suggestion the NCP1377
does the TI have the same function device…
You can use pin to pin device UCC28C42-Q1, which has a Tj up to 125C.
Besides, you can also consider these devices such as UC1842, UC1842A,UC1843A, UCCx800, UCCx802, and UCCx803, UCC2813-0/-2/-3-Q,..........Maybe it needs a little circuit mod…
