OK, that’s all for the Teardown of Apple 140W GaN USB-C charger. Let’s take a “family portrait.”
Summary of ChargerLAB
As the first charger that supports USB PD3.1. This 140W GaN charger still maintains Apple’s consistent high quality. Most of the controllers and MOSFETs are customized models and come from internationally renowned manufacturers such as ST, Infineon, ON Semiconductor, Toshiba, etc.
In addition, there are two GaNFETs, which is the first time Apple uses GaN chips in their chargers. And the electrolytic capacitor for filtering comes from Japanese Rubycon.
Until now, we can understand why it can be sold for $99.
As the industry leader, the first PD3.1 and GaN charger from Apple means more and more manufacturers will follow up very quickly. Hope more devices and chargers can support PD3.1 in the future.
