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 amplifier…
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 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…

This is a block diagram of a CCM PFC. I want to understand the role of the feedforward constant block here.
This is the functional block diagram of UCC2818A-Q1. Can anyone explain how…
Part Number: UCC2818A-Q1 1. How can we shut down the PFC or derate the PFC through microcontroller in case of Temperature of MOSFET going High?
2. How can we shut down the PFC or derate the PFC through microcontroller in case of Input Voltage dropping…
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 auxiliary…
