Hi, welcome back to today's ChargerLAB.
Today, we gonna teardown a Dell 60W mini GaN charger.
Did you remember that we have torn down the first Dell 90W GaN charger before?
If you haven't seen it, you can click the upper right corner to view it.
Compared to the 90W model, which still adopts the traditional size,
this one is much smaller and easier to use.
So, let's start from the beginning.
When you first look at the charger,
You may feel it's just a mini version of 90W charger without the cable.
The indicator light is near the output. The specs information is printed on the back.
Model is HA60NM200.
It supports input of 100-240V~50/60HZ 1.7A
and output of 5V3A, 9V3A, 15V3A, 20V3A.
Manufactured by Chicony Power.
It also passed different safety certifications, such as CCC,
CE, CP, EAC, UKCA, GS, UL, PSE, NOM, KC, TUV., etc.
Here is the standard 3-prong receptacle,
including the ground wire.
And the other side adopts the detachable design, USB-C port.
So, you can even use your own USB-C cable.
The length of the adapter is 66mm (2.6 inches).
Width is 55mm (2.17 inches).
And thickness is 22mm (0.86 inches).
Compared to Apple 61W charger, the size is much smaller.
The weight is about 101g (3.56 oz).
Then, let's use ChargerLAB POWER-Z KT002 to test the protocol.
USB-C only supports PD3.0
And it can support four PDOs of 5V3A, 9V3A, 15V3A, 20V3A.
Then, let's use the spudger to open it.
Em, failed.
Let's use the cutting machine to do it again to save some time.
The charger module is covered with copper heat sink.
And the insulating plate is between the heat sink and the components.
The heat sink is fixed by clips. And then remove it.
The ground wire is protected by insulating tube and across the primary and secondary circuits.
ChargerLAB found this charger adopts the high-frequency ACF topology,
and uses the protocol chip to control the output voltage.
Let's start to analyze the internal components.
The specs of time-delay fuse are 3.15A 250V.
The capacity of safety X capacitor is 0.33μF.
This common mode choke is used to filter out EMI interference.
The other one is wound by two wires.
Here is the bridge rectifier.
And this is the filter inductor.
The electrolytic capacitor comes from SAMXON, 400V 100μF.
The capacitor of master control chip comes from LTEC.
35V 56μF.
The master control chip adopts Texas Instruments UCC28782,
which is a high-density active clamp flyback (ACF) controller
with EMI dithering, X-Cap discharge, and bias power management.
The maximum operating frequency can reach 1.5MHz, and the efficiency can beyond 93%.
It also supports over-heating, over-voltage, over-current, short circuit protection.
This is the half-bridge driver. Model is ON Semiconductor NCP51530.
It is a 700 V high side and low side driver with 3.5 A source & 3 A sink current drive capability
for AC−DC power supplies and inverters.
It can offer best-in-class propagation delay,
low quiescent current, and low switching current at high frequencies of operation.
Those two GaN ICs on the primary circuit come from Navitas and adopt the QFN 5*6mm Package.
This one is Navitas NV6115, which integrates the driver and complex logic control circuit.
And switching frequency can be up to 2 MHz. 170mΩ, 650V.
The other one is Navitas NV6117,
which also integrates the driver and complex logic control circuit.
And switching frequency can be up to 2 MHz. 120mΩ, 650V.
Here is the transformer.
The optocoupler adopts EverLight EL1018, used to communicate and regulate output voltage.
Here are four SMD Y capacitors.
The synchronous rectifier controller comes from MPS MP6908A.
The maximum switching frequency is 600 kHz.
It supports different working modes and can work with standard and logic level synchronous MOSFETs.
The synchronous rectifier adopts Infineon BSC093N15NS5, which adopts G-TDSON-8 package.
150V, 9.3mΩ.
Here is the 1R0 filter inductor.
The specs of solid capacitor are 25V 680μF.
The protocol chip is a customized model, marked with DPD021P.
The nearby thermistor can detect the internal temperature.
This is AOS output VBUS MOSFET, marked with 32308C.
Finally, the durable USB-C receptacle is protected by steel plate.
Well, that would be all components of this Dell 60W GaN charger.
The detachable cable design is the most attractive feature,
making this charger more like a phone charger than a laptop charger.
And you can choose any USB-C cable you'd like.
It also integrates two Navitas GaN ICs, which can effectively reduce the size.
And all components come from well-known brands.
OK, that's all for today's video.
You can click the corners to view the teardown of Dell 90W and 130W power adapter.
