As the first 200W charger designed for mobile phone,
the iQOO 200W GaN Charger can fully charge the iQOO 10 Pro within 10 mins.
Pretty impressive.
You can click the upper right corner to check our test video if you're interested.
To achieve 200W fast charging, you must use this original charging cable.
It looks like a typical white cable, but the 10A mark means it can support 10A current.
It doesn't adopt full-pin design.
And the length of the cable is about 1.5m (4' 11.1'').
The ChargerLAB POWER-Z KM002C shows this cable also supports 100W PD fast charging.
The charger adopts rounded corners, and 200W is marked here.
The input prongs cannot be folded.
And we can also see some specs info.
Model is V200100L0B0.
The input and output can be divided into two parts.
You can pause to take a look.
And we find it only supports 20V 3.25A PDO, which is a 65W PD charger.
Manufacturer is AcBel Polytech.
It only has a USB-C port at the top.
The size of this charger is about 61 x 56.4 x 29mm (2.4 x 2.22 x 1.14 inches).
And the power density is about 2.01W/cm³,
setting a new record in the mobile phone fast charging industry.
Compared with Apple 140W GaN charger, the size difference is obvious.
The Weight is about 150g (5.29 oz). And about 211g (7.44oz) with cable.
The KM002C shows it can support QC2.0, QC5, vivo flash charge, PD3.0, and PPS protocols.
And it also supports five fixed PDOs of 5V3A, 9V3A, 12V3A, 15V3A, 20V3.25A, and a set of PPS.
The current can be almost 10A when charging the iQOO 10 Pro.
And the peak power is 178W.
Next, try to take it apart and check what's inside.
Firstly, pry along the gap and remove the top case.
And then, pull out the internal module.
We can see lots of silicone adhesives on the front.
Take a closer look at the input red and black wires connected to the input prongs.
The plastic plate and aluminum heat sink are on the back for heat dissipation.
And the heat sink for the planar transformer and rectifier is on the side.
After cleaning up the PCB, we can see the input fuse, capacitor, and transformer are on the front.
Flip to the back.
The master control chip, Navitas GaN IC, and other components are soldered on the back.
The charger adopts ZVS flyback topology and has a PFC circuit.
Let's introduce all components one by one.
The input fuse is from WalterFuse. 3.15A 250V.
The NTC thermistor is marked with SCK 012A, used to suppress the inrush current.
The first common mode choke is on the input fuse, used to filter out EMI interference.
The orange safety X2 capacitor is used to suppress differential mode interference, from CARLI.
0.33μF.
The second green common mode choke is next to it.
Next, the bridge rectifier from Pingwei GBL610 can convert AC into pulsed DC.
6A 1000V.
Two film capacitors are used for output filtering. 0.82μF 450V.
And the filter inductor is between two capacitors.
Flip to the back.
The TVS diode is used to suppress the induced voltage.
And the PFC controller is from ON Semiconductor NCP1623.
The GaN IC for PFC boost is from Navitas NV6136A, which adopts QFN 6*8 package.
It integrates driver and current sampling circuit to eliminate the loss of sampling resistor.
The switching frequency supports up to 2MHz. 170mΩ, 700V.
The PFC boost inductor is wound with Litz wire to reduce high-frequency losses.
Two PFC boost rectifiers are ultra-fast recovery diodes, and connected in parallel.
600V, 3A. ES3JBF
Here is the AiSHi electrolytic capacitor. Heat-resistant is 105°C.
420V 82μF. And this is a high-performance
digital flyback master controller. Model is Dialog iW9802.
The GaN IC for flyback topology is the same model as that for PFC boost.
The auxiliary MOSFET is next to the GaN IC we just mentioned.
It's from Semipower and adopts DFN5*6 package
650V, 1.1Ω. SW7N65D
Here is the transistor for voltage regulation, marked with BH.
This small TEAPO capacitor can power the primary controller.
10µF 100V. And the other one is from AiSHi.
50V 10μF. Two SMD Y capacitors are from TRX
and connected in series. TBY2331KB
And here're two more TRX SMD Y capacitors. TBY2101KB
The COSMO 1019 optocoupler is used to control the PFC boost.
Another optocoupler is used for output voltage regulation.
The planar transformer is soldered on the main PCB to reduce the thickness.
The synchronous rectifier controller is from MPS MP6908A.
The operating frequency can be up to 600KHz. Two synchronous rectifiers are from Vergiga,
which adopts PDFN 5x6 package. They are connected in parallel.
100V, 3.8mΩ. VSP003N10HS-G
Two solid capacitors are soldered on the small PCB for output filtering.
Those two solid capacitors are on the other PCB.
560μF 25V. And the USB-C socket is in here.
The protocol chip is on a small PCB and from Richtek.
A thermistor is on the right side to detect the temperature.
The Vergiga output VBUS MOSFET is on the back and adopts PDFN3333 package.
30V, 3mΩ. VS3698AE
And finally, let's take a closer look at the USB-C socket.
Well, that's all components of this iQOO 200W GaN charger.
The size is slightly larger than the iQOO 120W GaN charger,
but the power density is significantly improved.
It can support 200W ultra-fast charging for iQOO 10 Pro.
But for other PD devices, the output can only be up to 65W.
We found it adopts ZVS flyback topology and has PFC circuit.
It also integrates two Navitas GaN IC for higher integration.
