Part Number: UCC2808A-2 Hi Dear Support!
I'm trying to run the device from WEBENCH designer, here's the link:
webench.ti.com/.../SDP.cgi COPY
The problem is UCC2808A-2 is not reacting for changes of Vin and (or) Vout. I have tested circuit with…
Hi Hong Huang,
Hmmm, I checked the link and on my computer it's redirecting me to my scheme with UCC2808AD-2D. I will try to rewrite the link, if it wont work anyway, I will write parameters, that I used to generate scheme.
It is definitely UCC2808A…
Part Number: UCC2808A-2 Please let me know about how to calculate power dissipation for UCC2808A-2 or the other Push-Pull PWM.
If there better that available application note or calculation tool.
Best regards,
Satoshi
Part Number: UCC2808A-2 Hi,
My problem is ucc2808a2's error amplifier open loop gain test. Somewhere between 0.35 and 1.2 volts on the COMP pin. you will start to get pulses. at the comp voltage increases the pulse widths will get larger. Beacuse…
Hi Choi,
Thanks for bringing this to our attention.
The last line in the table should be UCC2808A-2.
We will add this to the documentation queue to update the datasheet.

Hello Watchaphong,
You could use the LM5030 for such an application however 100kHz is below the minimum operating oscillator frequency of the ic.
You should consider using the UCC2808A-1 or the UCC2808A-2 which is another push pull controller and can be…
Dear Colin,
thank you for reply,
1) what is "Transformer inductance" & "Inductance" marked RED color (my earlier screenshot) ?
2) Can you give a quick comparison about UCC2808A & LM5033 which is more suitable for me ?
I have…
Hi Alon,
It meant ambient temp rather than junction temp. 87C Ambient temp exceed max recommended operating range of UCC2808-2. Can you lower the ambient temp to see where the part starts switching?
For the UCC2808A-2Q1, I compared it against UCC2808A…
Part Number: UCC2808A-1 Is it possible to achieve a circuit of Fig.2 of ucc2808 data seat? The input voltage area which is 72V from 36V by Push - Pull system, can it correspond?
