Part Number: UCC2818A Other Parts Discussed in Thread: UCC28180 Tool/software: Hi,
TI's website states that it is not recommended to consider UCC2818A for new use. Please let me know if there are any points to note when replacing UCC2818A with UCC28180…
Part Number: UCC2818A Tool/software: Hello guys,
One of my customers use UCC2818A for their mass-production.
They found a phenomenon where the SS voltage does not rise above 1V. We know I know that this occurs when the capacitor between SS and GND has…
Hello Aravind,
Your calculation for Rff and Cff should follow the design method in the UCC2818A-Q1 datasheet. I'm not sure how design a 2-pole VFF filter on this device.
Your simulation is of a voltage source driving a series R-C filter. It is not…
Part Number: UCC2818A Other Parts Discussed in Thread: UCC2818 Tool/software: Hello guys,
One of my customers is evaluating UCC2818A for their new products.
At this moment, they have the following questions. Could you please give me your reply?
Q1. The…
Part Number: UCC2818A-Q1 Hello Team,
We require clarification in one of the datasheet parameters of UCC2818A-Q1 PFC Controller IC.
In the below image, the datasheet talks about power limit (IMOUTxVFF).
Can we know what exactly the parameter describes…
Part Number: UCC2818A Hi,
I have a question about startup behavior. Because the output voltage is rising rapidly, the output voltage has reached the specified value (380 V) before the end of soft start. I suspect that this is because the duty at startup…
Part Number: UCC2818A Hi,
Is there a tool (Excel) that calculates the setting values of peripheral components and devices when I input the input/output voltage and output current set as specifications?
Also, are there any design documents other than those…
Part Number: UCC2818A-Q1 Other Parts Discussed in Thread: UCC2818A , UCC2818 Hi again,
I tried to supply the IC with a solution similar to the one at pag.11 of the UCC2818A-Q1 datasheet: startup resistors + auxiliary winding on the boost inductor.
The…
