这个iPhone 11 Pro Maxships with the Apple 1720 18 W USB-C power delivery charger. This device is rated to delivery 5 V and 3 A or 9 V and 2 A. In follow up to our recent博客关于各种售后交流适配器，我们决定看看里面的苹果产品。
18W A1720为4.3cm×4.3cm×2.7cm，相当于50cm三（或3.0英寸三)因此，功率密度为6 W/in三,which is only ~1/3 the power density achieved by the market leading Innergie 60C charger.
Cracking open the case of the A1720 we find a densely packed collection of electronic components mounted on a PCB. The backside of the PCB features a Cypress Semiconductor CYPD313532L-QXQQ and an Alpha & Omega AO32394E power MOSFET. The front side of the PCB is densely packed with three electrolytic capacitors, an inductor coil and a transformer. Removing these devices revealed two more packaged components, namely a Power Integrations SC1263K6 active flyback controller and an Infineon BSZ096N10LS5 100 V N-channel power MOSFET.
