Hi, Welcome back to ChargerLAB.
Today, we got a new charger module,
which is made by Innoscience.
As we all know, most of the 100W chargers can only output 100W for one device.
If you charge two devices at the same time, the power will drop to 65W or 45W.
To solve this problem, so this 200W charger module is in here.
It has three USB-C and two USB-A.
If you charge two devices at the same time,
both devices can be charged at 100W.
And if you have three USB-C devices,
the output will be 100W+45W+45W.
And the USB-A can support up to 30W.
Then, let’s take a closer look at this module.
ChargerLAB found it adopts the architecture of PFC and LLC.
The power supply can output the fixed voltage.
And there’re four independent secondary step-down circuits, responsible for five USB interfaces.
And the length, width, and height are 76*74*21mm (2.99*2.91*0.82 inches).
Without the shell, the power density can reach 1.61W/cm³.
Compared with Apple 96W,
the size is almost the same. And it’s slightly thinner.
Then, let’s try to test its actual performance.
At 90V AC input,
The efficiency of 25% load reaches 92.6%,
and full load efficiency reaches 94%
At 230V AC input,
The efficiency of 25% load reaches 93.7%,
and full load efficiency reaches 96.4%.
It can effectively reduce the temperature problem at full load.
Then, here is the efficiency test results under different voltages.
You can pause to take a look.
Then, let’s see the actual temperature when this module is working.
The testing condition will be 90V AC input, full load, 2 hours,
and the environment temperature is 28.8℃ (83.3℉).
The LLC transformer is 92℃ (197.6℉).
LLC resonant inductor is 95℃ (203℉).
The electrolytic capacitor for output filtering is 76℃ (168.8℉).
PFC inductor is 91℃ (195.8℉).
Turn to back; the PFC GaN FET is 114℃ (237.2℉).
Two LLC GaN FET are 99.8℃ (211.6℉)
and 95.6℃ (204℉) respectively.
The synchronous rectifier is 95.5℃ (203.9℉).
The bridge rectifier is 113℃ (235.4℉).
The PFC diode is 105℃ (221℉).
During testing, the bridge rectifier and PFC diode need additional heat sink for heat dissipation.
There’s a vertical PCB to save space.
Those three bridge rectifiers come from Yangjie YBSM6010,
which can evenly dissipate heat.
Withstand voltage is 1000V, rated current is 6A.
The master control chip comes from MPS HR1211.
It’s a multi-mode PFC and current mode LLC combo digital controller.
It can replace 2-3 traditional chips and reduce the external components.
The CapXon capacitor of master control chip is on the edge of the PCB.
100μF, 25V.
The PFC switch transistor comes from Innoscience INN650D260A,
which is the GaN FET, and adopts DFN8*8 package.
260mΩ, 650V.
Compared to previous Innoscience GaN FET, this one is smaller and has better performance.
PFC boost rectifier is silicon carbide diode,
which comes from Global Power Tech G3S06505R.
650V, 5A.
It supports 175℃ and can be used for inverters and electric vehicle chargers.
Four filtering capacitors are welded in parallel on the small vertical PCB.
The PFC circuit can reduce the capacity of the capacitor.
So the charger can be smaller.
Those two LLC resonant switching transistors come from Innoscience INN650D260A.
And this is the LLC resonant capacitor from JURCC.
630V, 0.022μF.
The LLC synchronous rectification controller comes from MPS MP6924,
which can drive two synchronous rectifiers and adopts SOIC-8 package.
It supports fast shutdown, and multiple working modes.
It also supports 35V output and can work with logic and standard voltage synchronous rectifiers.
Two synchronous rectifiers come from ON Semiconductor NTMFS5C628NL.
60V, 2.4mΩ.
The SMD Y capacitor comes from TRX.
It has a small size, large capacity
and is suitable for mass production.
Those two solid capacitors for output filtering come from BERYL BC series.
1000μF, 25V.
All three USB-C can support 100W output.
The VBUS switch transistor, step-down inductor, and a solid capacitor are welded on the small PCB.
This is a synchronous step-down controller.
Model is Ismartware SW3516H.
It supports dual interfaces and independent current limit.
It also integrates 5A step-down converter and can be used in 65W-100W chargers.
Two MOSFETs from AOS AON6354 are used for synchronous rectification and step-down.
30V, 3.3mΩ.
The solid capacitor for output filtering comes from Yongming NPX series.
220μF, 25V.
This series has a small size, low ESR.
Well, that’s all components of this charger module.
The size is not very small, but its power has reached 200W.
So, if you compare it with two 100W chargers, you can see its advantage.
And if you have two laptops or another Android phone, you can charge them at full speed.
It adopts the architecture of PFC+LLC,
which is the small size and high-efficiency power supply design.
And the secondary step-down circuit at output is very flexible.
Different manufacturers can make different choices according to different product positioning.
OK. That’s all for today’s video.
