Hi, guys. Welcome back to ChargerLAB.
Today, we’re going to teardown a special charger, the car charger.
You’ll know that if you drive to work.
This charger comes from Baseus, which is equipped with two USB-C and one USB-A.
If you charge three devices at the same time, the maximum power can be up to 160W.
So, let’s start today’s video.
Firstly, we can see the QC5 logo at the top.
Yeap, this is a QC5 certified car charger.
We also teardown the world’s first QC5 100W charger before,
which was also produced by Baseus.
You can click the right corner to check it out.
Back to this product, it’s composed of two parts of plastic shell.
Here is some information.
You can pause to take a look.
But we need to notice that the charger can output 15V / 20V only under 24V input.
It also passed FCC and CE certifications.
This is the positive pogo pin.
And negative pogo pins are on both sides.
We can see it has two USB-C ports and one USB-A port.
The QC5 and 100W logos are printed around USB-C1 (the top one).
It weighs about 47g (1.66 oz).
Considering the 160W, so the size is relatively small.
There is a circle of blue LED light around the edge of the front.
Then, use ChargerLAB POWER-Z KT002 to test the USB-C1.
We can see it supports Apple 2.4A, QC2.0/3.0, AFC, FCP, SCP, PD3.0, PPS protocol.
It has five fixed PDOs of 5V 3A, 9V 3A, 12V 3A,15V 3A, and 20V 5A.
and one PPS PDO of 3.3-21V 5A.
The USB-C2 has the same protocol as C1,
but supports two PPS PDOs of 3.3-11V3A and 3.3-16V2A.
Finally, USB-A supports QC2.0/3.0, AFC, FCP, SCP, PE2.0 protocol.
Then, let’s tear it down.
Remove the top case firstly.
We can see the LED light.
And every single USB port has its own PCB, and is filled with thermal pads.
Take out the car charger module.
Two PCBs are connected by the input PCB and fixed by the input pogo pin.
A long-strip thermal pad is attached to the PCB.
Insulation tape is attached to all three USB ports.
Split the module, and we can also see the thermal pad.
There is a buck-boost controller on the front of the small PCB where the USB-C1 port is located.
And there are four MOSFETs, output filter capacitor, filter inductor, and protocol chip.
The input filter capacitors and buck-boost inductors are on the other side.
The input filter solid capacitor comes from Yunxing Electronics.
35V 100μF.
“YX” solid capacitors are specifically designed for USB PD fast charging.
It also has the characteristics of high temperature resistance, large ripple resistance, low ESR, etc.
This is a 100W synchronous buck-boost controller, which comes from Powlicon PL5501.
It can support input of 3.6-32V and 20A current.
It can also stably regulate the output voltage
when the input is higher or lower than the output voltage, expanding its applications.
Those four external MOSFETs form an H bridge, driven by PL5501.
One of them is ADAMANT AD30N80D5, which is 30V, 2.1mΩ and adopts HSOP8 package.
The output filter capacitor is also from Yunxing Electronics.
25V 150μF.
And filter inductor is next to it.
The protocol chip of USB-C1 adopts Injoinic IP2726,
which integrates multiple protocols and is used for USB output.
With high integration and rich functions, it can effectively reduce the size of the charger and the cost.
This chip also passed QC4+ certification.
Let’s move to the second PCB.
The front of the PCB is equipped with input filter capacitors, two step-down inductors,
and two output filter capacitors, used for USB-C2 and USB-A separately.
This is the positive pogo pin to connect the input power.
The input filter capacitor is also from Yunxing Electronics.
35V 100μF.
There are two protocol chips on the back of the second PCB.
And this is the step-down protocol chip of USB-C2,
which comes from ismartware SW3522.
It integrates multiple fast-charging protocols
and 3.5A high-efficiency synchronous buck converter.
Only a few components are needed to complete the charging solution.
This is the step-down protocol chip of USB-A, which comes from ismartware SW3521.
It’s also a highly integrated buck converter and supports multiple fast charging protocols.
The step-down inductor is wrapped with an insulation tube.
This solid capacitor is 25V, 100μF, used for output filtering of USB-C2.
This pink one is used for output filtering of USB-A, which comes from APAQ.
16V, 100μF.
And the USB-C2 port is soldered on the small vertical PCB between two main PCBs.
Finally, a total of 12 LED lights are on an additional small PCB.
Well, that’s all for the teardown.
This car charger is composed of five small PCBs.
There are three independent buck and boost circuits on two main PCBs.
The ismartware SW3522 of USB-C2 and the ismartware SW3521 of USB-A are highly integrated.
That’s the reason why they can share one PCB, which can reduce the size.
In addition, there are also thermal pads on the PCB to dissipate heat and reduce temperature.
OK, that’s all for today’s video.
By the way, Apple is going to launch its second event of this fall.
Let’s see what new products will be released.
See you in the next video.
Bye.
