Hi, guys.
Welcome back to our channel.
Actually, Apple released two brand new chargers in the October Apple event.
And this is the 67W charger that is compatible with 14 inches MacBook Pro.
Today, chargerLAB will try to tear it down to see what's inside.
And what's the difference between 67W and the previous 61W.
By the way, I still want to remind those who haven't seen the teardown of Apple 140W charger
can click the upper right corner.
Firstly, let's unbox it.
There're some documents and the charger.
The charger is square and adopts the smooth white shell.
Foldable pin and replaceable plug.
The corners are rounded,
and there's only one USB-C port.
Model is A251.
Manufacturer is Lite-On Technology.
It can support input of 100-240V~50/60Hz 1.65A and output of 5.2V3A, 9V3A, 15V3A, 20.3V3.3A.
Compared with Apple 61W charger, The size and appearance are very similar.
The length, width, and height are 73*74*28mm (2.87*2.91*1.1 inches).
The weight is about 205g (7.23 oz).
Use ChargerLAB POWER-Z KT002 to test the protocol.
It supports Apple 2.4A, Samsung 5V2A, DCP.
Unlike the Apple 140W, it still uses PD2.0.
And we can see it supports four fixed PDOs of 5V3A, 9V3A, 15V3A, 20V3.27A.
Then, let's see its compatibility.
Next, let's tear it down.
We can see the heat sink and thermal adhesives are covered on the PCB module.
Take out the internal module.
Except for the live wire and the neutral wire,
there's an additional ground wire connected to the PCB module.
The USB-C port is connected to the PCB through a flat cable.
Continue to remove the heat sink.
And then, let's speed up.
Ok. Here is the front of the PCB.
We can see capacitors, transformers, rectifier bridges, etc.
An L-shaped metal heat sink is on the side.
And the SMD components are on the back.
This is the fuse.
And the common mode chokes are used to filter out EMI interference.
This is the safety X2 capacitor.
The varistor is used for input overvoltage protection, marked with TVR10561M.
The input bridge rectifier comes from Lite-On GBL408.
4A, 800V.
The electrolytic capacitor comes from Rubycon CXW series.
Specification is 400V 150μF.
Two small electrolytic capacitors are also from Rubycon.
And they are 50V 22μF and 100V 68μF respectively.
The primary PWM controller comes from ON Semiconductor NCP1340 and adopts SOIC-8 package.
This is a highly integrated quasi-resonant flyback controller,
which is suitable for high-performance power converters.
The primary MOSFET comes from Infineon IPA80R450P7.
800V, 0.45Ω.
This is the transformer.
Two optocouplers are on the back, used for feedback circuit of output voltage.
Those two Y capacitors are used for output anti-interference.
The secondary synchronous rectifier controller comes from ON Semiconductor NCP4305,
which supports up to 1 MHz operating frequencies and is applicable to mainstream topologies,
such as Flyback, LLC, Forward, etc.
There's a Toshiba synchronous rectifier MOSFET on the corresponding position of the back.
Model is TPH4R10ANL,
100V, 3.3mΩ.
This solid filter capacitor is at the output.
390μF 25V.
Another TAICON electrolytic capacitor is next to it.
25V 820μF.
There is a customized protocol chip on a small PCB,
which comes from Infineon CYPD3135,
which belongs to CCG3 series and is responsible
for USB PD communication.
The VBUS switch transistor at the output comes from ON Semiconductor NTMFS4C022N,
improving the charger's efficiency.
Finally, here is the USB-C port.
Well, this brand new Apple 67W charger is actually based on the Apple 61W charger.
So, there is almost no change in its appearance and internal layout.
Seems like it only updated the firmware of the protocol chip.
So, it can output 3.3A current under 20V voltage.
However, its internal components are all from well-known brands,
and the quality is pretty good.
Ok, that's all for today's video.
Until now, we've teardown Apple's 20W, 30W, 67W, 96W, 140W PD charger.
