Part Number: UCC2808A-1 Other Parts Discussed in Thread: UCC2808-1 Can you comment on the following questions:
1) OUTA/OUTB Source Current: The UCC2808 lists -0.5A as a minimum whereas the UCC2808A lists -0.5A as a maximum. Is this an error? Should they…
Part Number: UCC2808A-1 Hi
The physical marking of this product is UCC2808, but according to the datasheet, there are UCC2808A-2EPH and UCC2808, please confirm why there are two different marking information?
T hank you
Part Number: UCC2808A-1 Hi
I saw the typical application from datasheet of UCC2808AD-2,so can anyone help to explain below:
Q1: what is ① used for ?
Q2:why add an inductor connected to GND as noted with ② ?
thanks
Thanks for your reply. I have another question, is there a way to make sure the ton on the UCC2808A-1 never goes below below a certain width even if the feedback is full ?
Part Number: UCC2808A-1 Other Parts Discussed in Thread: UCC28083
Is UCC2808A or UCC28083 able to be configurated with open loop control? It means there is no feedback from output voltage, in stead it's used a fixed voltage supply to CTRL pin. if so,…
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: UCC2808-2 Other Parts Discussed in Thread: UCC2808-1 Hi,
I use the chip UCC2808-2 and I would like to fix the duty cycle about ~40%. How to do it ?
I'm confused with COMP and CS pins functionnality. I read that "The CS pin is for duty-cycle…
Part Number: UCC2808-1 Other Parts Discussed in Thread: UCC2808A-1 , Do we have TINA SPICE Model for UCC2808-1 and UCC2808A-1? If not what is the nearest equivalent part available. I want to simulation Isolated DC DC Conveter Push Pull Topology 300KHz. …
