Part Number: UCC2808A-2Q1 Our customer consider to use UCC2808A-2Q1.
We got following questions from them. Please advise us.
1) When the CS terminal detects the threshold, the DUTY of the OUTA or OUTB output is reduced as shown in the attachment. Is this…
Hi Steve
I want to know exactly what the input voltage range is for the UCC2808A-2
1. Datasheet Contents
2. Web page content
I wonder why the content of the webpage and the datasheet are different.
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?
Part Number: UCC2808A-1 Hi Team
for UCC2808A, calulating the proper sensing resistor is by { TYP overcurrent threshold[V] / OverCurrent[A] = 0.75V / OverCurrent[A] } ?
Hi Eric,
Thanks for your replies again!
(1)We add a sliding rheostat to the FB pin of UCC2808A-2 for testing according to the method you recommend. We found that when the voltage on FB pin rises to 2.0V, the output pulse of UCC2808A-2 will turn off…
Other Parts Discussed in Thread: UCC2808A-1 I have quetions of UCC2808A-1.
1. stability
I think UCC2808A-1 is the voltage control by the width of ON time. Is this correct?
If it is correct, I think it is difficult to keep the stability of the wave shape…
Other Parts Discussed in Thread: UCC2808A-1 , TL431 Hi,
i will build a unregulated Push-Pull-Converter with the UCC2808A-1.
At fixed 200kHz it should run at nearly 90% Duty-Cycle.
The Current should be limited at nearly 1,2A.
I'm a little bit confused…
Hi Kato-san,
You can consider using the UCC28C44 or the UCC2808A, family of parts.

Dear TI
I think ucc2808a pdf has a wrong information in table 1.
Second line , UCCx808A-1 --> UCCx808A-2??

Part Number: LM5030 Other Parts Discussed in Thread: UC2827-2 , UCC2808A-1 , UCC2808A-2 Dear TI Team
I would like to step up 12VDC to 350VDC ~ 380VDC (300W and Peak load 600W). and i choose LM5030 for push pull converter.
i have few questions to ask 1. LM5030…
