What did they use to allow for such a small transformer? Frequency increase?
Enhance has a patent on that transformer design. They can make really small transformers for high power, high temperature applications.
It's also a feature of the Champion CM6901 controller.
Well... the CM6901 has been used in almost everything LLC for ages. Doesn't mean you can get away with using a smaller transformer if you expect your PSU to put out 1200W at 50°C.
Seems like it these days.
Take Corsair for example. Even the CS-M uses that IC and soon, the new CX (non modular as the modular version just got refreshed a few months ago) will as well!
A CX series with LLC resonant converter?
Don't get too excited. We're talking an end of the year product.
But it's just an example of how important these higher end technologies are, even though they're more of a niche product than and only sell 1/10th of what the rest of the product volume is. And it's not as if the CX customer would care.
It was only 10 to 15 years ago when we saw non-PFC, double-forward with no DC to DC as the norm for the mid range product.
What is the main reason for LLC in lower-end series? DC-DC was pretty obvious, but primary?
