Part Number: UCC2818A-Q1 Tool/software: Guys
The typical circuit for synchronizing the UCC2818A-Q1 to an external clock is shown in figure 7 in the specification and is based on adding a pulse on the voltage on CT. The maximum value of the ramp peak…
Part Number: UCC2818A-Q1 Hi team,
Iam using UCC2818A-Q1 Part for my deisgn.
I couldnt find the any excel calculator, reference design, application nnotes.
I found one mathacd file which is in XMCD format.
Could you please convert this file…

Hi Team,
Please tell me the gain of the voltage error amplifier shown in the typical application of UCC2818A-Q1 datasheet and what is the output of the voltage error…
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-Q1 Hi Team,
I am Planning to use part UCC2818A-Q1 for 750W charger application. my input range is 170 to 270VAC.
Can you share the design calculation guidelines documents and design tool ?
Part Number: UCC2818A-Q1 Hello,
I made a boost rectifier with UCC2818A-Q1, Vout 385V, 1kW.
Actually the IC is supplied with 12V from the external but I would like to supply it from mains as in the datasheet Figure 1 (pag.11).
I tried to made some…
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. …
