It says in the article: >> The company says it uses Weltrend WT6676F, ON Semi NCP1622, and JoulWatt JW1556 controllers, as well as GaN switching parts from both GaN Systems and Navitas “peaking at an amazing 93% efficiency” for this 180W adapter. Both those parts and Chicony’s assistance as a power supply manufacturer are obviously there for other companies to use as well. So likely even less efficiency for the higher rating. I'm very interested to see how they're venting this heat passively. |
