Those 65W Navitas based chargers are actually all exact copies of the reference design, and most are made by a single factory.
GaNFETs are there mostly for the marketing, and don't make any much more difference than few percents efficiency at such power level.
- aidenn0 6y agoI'd have to look at the numbers, but a few percent points of efficiency can be a big difference in the power (and thus heat) dissipation of the device; going from 90% to 92% efficiency reduces the power dissipated in the device by 20%.
