Part Number: UCC25630-1EVM-291 Other Parts Discussed in Thread: UCC28056 Ben-san,
Customer is now very upset.
Datasheet page 34, shows "These include Brown- Out (VZCBoRise),........"
I think the IC designer intended to BoRise = Brown-in.
But do…
Hi, Poh
Thanks for interesting in this reference design from SEM team, but this board TIDA-010038 is out of stock now.
But, the two TI EVM boards (PFC and LLC) could be applied, you can combine these two together instead.

Hi Julia,
UCC28056 can support up to 300W design , you can find in UCC28056EVM user guide test report that the THD is less than 7% at the load from 75W to 165W range when input voltage is 230Vac. here is the link of user guide.

HI Hiroshi Doi-san,
Thanks for your interest in PMP21251. Yes, a simpler method for mitigating inrush current is to have an NTC in either the EMI filter before the bridge or to the right of the boost diode D100.
As an example, the UCC28056EVM-296 includes…

These targets are reasonable for UCC28056. The EVM is close to these specifications, I recommend measuring the performance of the it to validate that the performance meets the targets.
You can get more information and order the EVM here www…

Hi
Our customer consider this device at low power. (Min ; around 5W. Max:~ 60W)
They are evaluating with TI-EVM (UCC28056EVM-296) now. Then they asked us.
As result, this device looks staring PFC operation more than 26W (at high…
Hello,
This UCC28056 use a transconductance amplifier. I reviewed the data sheet and their is no information in regards to gain bandwidth product. Generally these amplifiers are not designed for high frequency applications. The older TI PFC controllers…
