The master control chips are two LLC controllers.
They form a half-bridge resonant circuit to improve power conversion efficiency.
Two LLC MOSFETs are from SemiHow HCFL65R210.
It's an NMOS of 650V, 200mΩ,
and is in a DFN8*8 package.
The LLC resonant capacitor is 0.022μF and 630V.
Diodes are on the back of the transformer's PCB.
The filter capacitor, 35V 47μF.
The SMD Y capacitor is from TRX TMY1102M.
This is the 1009 optocoupler for voltage feedback.
The two synchronous rectifiers are from Hunteck.
It's an NMOS of 100V 8mΩ and is in a DFN5*6 package.
The secondary synchronous rectifier controller is from NXP Semiconductors TEA1995T.
It has two drivers for synchronous rectification of the LLC topology.
Two solid filter capacitors from JSH are 820μF 25V.
Four MLCCs in the 1206 package and solid capacitors are in parallel.
This is the output filter inductor.
A 220μF 25V filter capacitor follows the filter inductor.
A buck inductor is on the back of the USB PCB for the 5V output of the two USB-A ports.
The USB PD IC adopts the Weltrend WT6636F.
The USB-C port adopts the synchronous buck converter from Toll Microelectronic TMI2286D.
It's 30V in the SOP8 package.
The other USB-C port is the same.
The MOSFET from Hunteck HTM200P03 is to reduce the output voltage drop.
It's a PMOS of 30V 20mΩ and in a DFN3*3 package.
The output solid filter capacitor is 220μF 25V.
The other two used for input and output are also 220μF 25V.
The VBUS MOSFET from ARK is printed with 30N5P0S.
It's an NMOS of 30V 4.2mΩ and in the PDFN3333 package.
The other VBUS MOSFET is the same.
The buck controller for two USB-A ports is from Southchip SC8002.
The input filter capacitor is 150μF 25V.
Two synchronous buck MOSFETs from Huayi Microelectronics are between the two USB-A ports.
It's an NMOS of 30V 7.1mΩ and in a DFN3*3 package.
The buck inductor is fixed with adhesive and wound by two wires.
The USB-A ports adopt the SMEI CW3005F IC
and support Apple 2.4A protocol.
There are the sampling resistor and the LM321 operational amplifier for output power distribution control.
There are the other sampling resistor and LM321 operational amplifier.
The filter capacitor for USB-A port output is 150μF 6.3V.
The other USB-A port has the same filter capacitor.
The thermistor is covered with heat shrink tubing and insulated with heat-resistant tape.
Well, that's all components of the InfinityLab 100W GaN charger.
This charger comes with replaceable prongs of three standards, compatible in different countries.
It also has two USB-C ports supporting 100W and two USB-A ports supporting 5V,
meeting the needs of different devices.
Besides, it adopts powerful GaN components to make it smaller and better.
