Report Suggests Apple to Release GaN USB-C Charger With 65W Fast-Charge This Year

It's follow-on effects. GaN allows the switching circuit to run at a higher frequency, letting them use a smaller transformer, reducing the use of expensive copper wiring and the environmental impact of such.

$0.579 vs $7.48 ( Full Reel )

Despite the price has fallen for GaN, the gap is still huge. And it works in flavour when you are designing high wattage where get bigger saving from less cooling component.

And if you know anything about Apple's BOM and margin $7 increase is insane.

That is unless they are going to ship the iPhone with Graphene Battery which allow very high wattage charging. But Apple tends to be *very* conservative with battery advancement and implementation. ( As they should as it causes all sort of potential issues ) So using leading edge tech doesn't seems likely.

12.5 A transistor. That's a transistor for several killowatts. (12.5*340 V) Way overkill.

If you've been following the industry, all of these GaN charger chipsets come from Power Integrations, which has a single package controller with a GaN-on-Sapphire device, basically derived from white LEDs.

The fact that they're selling 60 W GaN chargers on Amazon for $25 says that cost is not a factor at this point.

So while those chargers might charge the MBP with them off, practically every review I've ever seen has suggested that they won't keep the laptop up if it's being used.

Depends on what you’re doing. For light duty (web browsing and such), even my Nintendo Switch power supply (39W) charges my 16”. In fact, a 10W iPad charger was enough to keep the battery level steady with light usage.

This is the GaN chipset in the 60 W chargers. $2.83 retail.


The Si version, one step down, is $1.05. So the difference is $1.78, not accounting for the savings of transformer copper, heatsinking, etc.


Meanwhile, Apple charges $69 for a 60 W charger. They can afford it.

This leads to design factors, which Apple is certainly interested in. The volume of the US 18 W iPhone charger right now is roughly 4-5x that of the original 5 W charger. I can see them wanting to shrink the size back down.

Heck... “I” want to see the size shrunk down!
