Part Number: PMP20795 Other Parts Discussed in Thread: PMP22087 Hi team,
My customer want to use PMP20795 to design a high efficiency DCDC, can you pls share the design file of the LLC transformer in PMP20795?
Thank you!

Part Number: PMP20795 Hi All --
I'm looking for a demo board or evaluation board for the PMP20795 (200kHz LLC Series Resonant Converter Reference Design). on TI, it says "Fully assembled board (shown above) developed for testing and performance validation…
Part Number: UCC256301 Other Parts Discussed in Thread: PMP20795 , UCC25630-1EVM-291 , UCC256304 Hi team
I started to study LLC in the last six months. The chip used is Ti’s UCC256301. Our design goal is:
Input voltage: 340V~410V Output voltage: 100V…
Hi Ernest,
Sorry my delayed response. The PMP7391 design uses output diodes. If the diodes were replaced with synchronous rectifiers and careful redesign 95% should be possible with an active clamp forward.
However, an easier path to a solution might…
Part Number: UCC256304 Other Parts Discussed in Thread: PMP20795 , , UCC256301 Hi,
Just started working with this IC and have had 5 pieces fail so far. The setup is based on PMP20795 reference design and i'm trying to power up from low voltage gradually…
Part Number: UCC256301 Other Parts Discussed in Thread: PMP20795 Dear Team,
My customer use PMP20795 as their reference for design.
I have to say, the design is almost the same.
Same transformer, resonant inductor and so on.
But the waveform…
Hi Ben,
My issue here is the output ripple which has some low frequency noise superimposed. The circuit i've used has tried to eliminate all possible sources of this noise and i'm left with the conclusion that the noise is coming from the controller…
Hi Robin,
Thanks for your interest in UCC25630EVM. This EVM was designed for a maximum output power of 120W. We currently do not have an orderable UCC25630x EVM that can support 250W.
One possibility is take the design files from an existing reference…
