Part Number: UCC28180 Tool/software: Hi,
We are currently considering a circuit that boosts from a rectified voltage of approximately 30V to around 170V. Since the UCC28180 does not directly detect the input voltage, we believe it could operate properly…
Part Number: UCC28180 Tool/software: Require unencrypted p-spice model of UCC28180 (.lib) for simulation purpose.
The available model is encrypted, and can not be imported.
Part Number: UCC28180 Tool/software: Dear ,
We are getting failure in CE test class A when we apply earthing (grounding and get pass when remove earthing .
Below is the wave form at without earthing
Below is the wave from with earthing .
Our product…

Dear Members,
We have utilized this chip in our Power Factor Correction (PFC) design. It operates with an input voltage range of 85VAC to 265VAC, and the maximum PFC voltage should be 440VAC with current of 3A and…
Thank you for your reply, but the actual situation is a little different from what you described, we see that D4 and D5 have completed full-wave rectification before D6, D6 does not play the significance of rectification, through simulation we can find…
Hello Ilavarasan,
Yes, the inductor ripple current at the PFC switching frequency normally adds Differential-Mode (DM) noise to the EMI signature and this noise is usually seen as a series of tall EMI peaks separated at integer multiples of the switching…
Part Number: UCC28180 Other Parts Discussed in Thread: UC3842 Tool/software: Hi team，
I am currently developing a boost PFC+flyback switching power supply. The PFC chip uses UCC28180, and the flyback uses UC3842.
1. The power supply for UCC28180 uses…
Please read the UCC28180 datasheet (especially section 8.3).
Please read this handbook to understand PFC principles: https://www.onsemi.com/pub/collateral/hbd853-d.pdf
