Part Number: UCC2808A-1 Hi,
The datasheet lists IDD < 10mA with VDD at 15V.
However the sink current peak at VOUTA and VOUTB is 1A.
Isn't this current supplied by VDD?
If that is correct, is the average IDD < 10mA because those peaks are supplied…
Part Number: UCC2808A-1 Other Parts Discussed in Thread: UC2843 , Dear Guys:
In soft start，Change UCC2808A Pin 1(COMP) PWM from 0% to 50%，The expected comp voltage is from 0V to 5V.
However, it is actually increased to about 1.5v, and this voltage will…
Other Parts Discussed in Thread: UCC2808A-1 I have quetions of UCC2808A-1.
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…
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…
Thank you for reply,
I tried same spec on my pc, unfortunately there is difference in current (marked RED color) on my screen ?
Could you please clarify , i attached screenshot.
1) what is "Transformer inductance" & "Inductance" marked RED…
