Part Number: UCC2818-EP Other Parts Discussed in Thread: UCC28180 , PMP31164 , UCC25640EVM-020 Tool/software: Hi TI team
We have build a PFC board using UCC2818-EP PFC IC.
Following is our requirement
Vin :100Vrms to 134Vrms (360Hz to 800Hz) …
Part Number: UCC28180 Hi Team,
Our customer built a board with UCC 28180D and noticed that there are some voltage spikes when the device is switching as shown in the attached video. His schematic diagram is similar to the one in the UCC28180EVM-573…
Hello,
Thank you for your answer.
I add brown in/out functionality.
Is there the calculation formula about soft start time?
Is the RC time constant of the VCOMP pin all right?
(From UCC28180 detasheet and UCC28180EVM-573)
Regards.

Hello,
I have designed a 2.5kW PFC using UCC28180.
While testing.it, on giving isolated 230VAC input(from mains without auto transformer). The output ceramic capacitors exploded and the test failed.
We followed the test procedure…
Hello,
Thank you very much for your recommendations.
Mostly, I referred to the Webench Power Designer of Ti and UCC28180 1KW PFC and UCC28180EVM-573 reference schematics
Sure, I knew about excel calculator but I choose Webench schematic.
I will…
Unfortunately, I have no visibility into the production data. I do know the TI factories are humming to keep up with demand across all products with new factories coming on-line as we speak. Samples will be the first to be replenished, but I would check…
Hello Suriya,
TI does not support LTspice models or modelling issues.

Hi Leon,
with special care of input filter, PFC inductor, PFC current loop, UCC28180 can easily support 0.99 PF value.
I suggest customer can order an EVM for evaluation.
in the EVM there are PF figure that shows at univisal input range, UCC28180…
Part Number: UCC28180 Other Parts Discussed in Thread: , LMG3410R150 I noticed on the UCC28180 data sheet that there is a single diode in the sample circuit. On the UCC28180EVM-573, there is an additional diode connected to the line side of the boost…
Part Number: UCC28180 Hi Team,
My customer is going to evaluate UCC28180EVM-573, and is considering current sense method. Usually, a negative voltage similar to the inductance current (triangular wave overlapped on the sine wave) is applied to the ISENSE…
