This is Toshiba MOSFET, which adopts DFN 8*8 package. This is the ON Semiconductor customized driver, used to drive Toshiba and Infineon switch MOSFET and marked with SC530C. The electrolytic capacitor for high-voltage filtering comes from Rubycon, 450V 82μF. The diode for PFC rectifier comes from ON Semiconductor FES10J. Those two MOSFETs are used for PFC boost, marked with 36N60PF8N. This is the PFC boost controller, NXP TEA19162T. The toroidal-core filter inductor is fixed by glue.Īnd the USB-C is connected to PCB by cable. Turn to other side, we can see film filter capacitors and magnetic ring filter inductor. Take a closer look at the Infineon MOSFETs, which are used to improve rectification efficiency. Those two diodes can cooperate with Infineon MOSFET for active rectification. Those four diodes at the input can form the full-bridge rectifier. This varistor is used for input overvoltage protection. The common mode choke is used to filter out EMI interference.Īnother common mode choke is winded by blue and black wires. There are two Infineon MOSFETs on the right.
The safety X capacitor is covered with a plastic, and the fuse is equipped on the top. We can see four diodes, two drivers, optocoupler, protocol chip, and output VBUS switch MOSFET are on the front.įlip to back, we can see PFC boost circuit, LLC switching power supply controller, and MOSFETs. The electrolytic capacitor is placed horizontally and covered with insulating tube.Īfter removing all the plug-in components, We can see the electrolytic capacitor for high-voltage filtering, current transformers, film capacitors, capacitor for power supply, etc. The back of the PCB is covered with a rubber pad for insulation and protection.Īnd the thermal adhesives and graphite thermal pads are on different chips. The capacitors, inductors, and other components are on the front of the module.Īnd the transformer is covered with plastic. Remove the heat sink, and we can see the internal module. The length of PCB module is 87.6mm (3.45 inches).Īnd the thickness is 23.2mm (0.91 inches). The insulating tape is pasted on the side. It fixed with screws and used to evenly dissipate heat. The large heat sink is covered on the PCB module. The solder joints of AC wire are insulated with heat-shrinkable tubes. This is the ground wire that is connected to the plug. Use the cutting machine to open the shell.Īnd those black glue is used to fix the module. It supports Apple 2.4A, Samsung 5V2A, DCP, PD3.0 protocolĪnd the supported five fixed PDOs are 5V3A, 9V3A, 15V3A, 20V4.7A, and the 28V 5A additionally.Ĭonnect it to the outlet and use ChargerLAB Power-Z KM001C to test, we can see it can reach 27.73V 4.92A 136.68W. Use ChargerLAB POWER-Z KT002 to test the protocols. The length of the charger is about 96mm (3.78 inches). You can replace the plug equipped with ground wire. You can conveniently change the plug you want to use.
It is still equipped with foldable pins and a replaceable plug. And the manufacturer is Flextronics Power. We will test and teardown this charger to answer those questions.įirstly, it continues the simple white shell of other Apple PD chargers and adopts the glossy surface, and the corners are rounded.īut compared to 81W, 87W and 96W, it changed from the traditional square to rectangle.
Many people are curious about the internal design, architecture of the first PD 3.1 GaN fast charger, and what kind of brand new components are inside. You have to use this cable to achieve 140W charging.Įxcept for this 140W PD charger, Apple has released ten PD chargers, from 18W to 140W. There is also a customized USB-C to MagSafe 3 cable. And it’s also the world’s first laptop that supports USB PD3.1 protocol, which makes it can support up to 140W PD fast charging. The brand new MacBook Pro 16 inch is equipped with powerful processors M1 MAX. On october 19, 2021, Apple held the special event, released AirPMacbook Pro, and also brought a new color for HomePod mini.
