Part Number: UCC28180 Other Parts Discussed in Thread: UCC2810 Good morning, I'm building a PFC CCM with your UCC28180 integrated circuit.
These are the rough specifications
Vin = 180-264V Vout = 400V Iout = 2 A
fsw = 110 kHz L = 250 uH (with 40%…

Part Number: UCC28180 Hi Team,
My customer is surveying suitable PFC solution supports 250Vac~800Vac input, 500W power level.
Could UCC28180 support this requirement? And is there any suggestion on circuitry configuration?
Regards,
Charles
Hi Venkatesh,
For UCC28180, for the loop transfer function of voltage and current, we have only whatever information is shown in datasheet and excel calculator in terms of theoritical expressions for this multiplierless PFC. I would suggest further looking…

Hello,
I tried to find an answer on the internet but wasn’t able to. So here I am ! I was trying to find a way to supply my ucc28180 and a convenient way would be to use a bootstrap…
Part Number: UCC28180 HiAll,
I have a question about UCC28180.
How much load fluctuation can you tolerate? Please tell me the load current slew rate, rise and fall times, etc.
I also have a question about the EVM of UCC28180. Please tell me why the input…
Part Number: UCC28180 Hi All,
I have a question about UCC28180.
Customers are evaluating using EVM. The input current waveform has distortion and noise at light loads. Is this waveform correct behavior? Is there a way to eliminate the distortion?
Best Regards…

Hi,
i am using UCC28180 IC for PFC operation,1KW power
Under No load PFC Voltage maintained at 415V as set,under minimum load PF is 94,while increasing Loading PF getting reduced and Current is distorted like this(attached image…
