Are there available the schematic and PCB design files for the PMP5327 reference design ? I saw that there are gerber files on the website, but I would need to to a larger board that includes this power supply and also do some modifications. And it would…
Hi, the crossover distortion is an inherent issue with buck PFC which occurs when Vout falls below Vin (see p10 & p11 in the datasheet). I don't know the details of your application but you may find the following app note useful: https://www.ti…
Mark,
I do believe PMP10215 is the best reference design you can leverage for your design since it provides you with the 36V,12V,and 3.3V rails you're looking for. It's rated for 200-W and has a peak power rating around 840W, so I think it should be ok…
Hi Vinesh,
PMP5327 is a reference design that uses the UCC28019A.
Attached are the schematic and test results.
You are correct that there is no TINA model available for this part.
Regards
John

Hi Chentsu Chung,
Thanks for your interest in UCC28019A. It is recommended to use an independent, regulated supply for VCC of UCC28019A. Take a look at PMP5327 as an example. It uses UCC2889 to implement a small, regulated bias for UCC28019A: www.ti.com…
Hey Richard,
I'm sorry about the error. Please find my question below:
My customer is working on " PFC,
Resonant Half-Bridge, Buck (PFC, 42V@6A) for Digital Audio" ( PMP5327)
I wanted to know the transformer specifications used on…
