The width of the PCBA module is about 27.5mm.
The height of the PCBA module is about 26.7mm.
Soldering and splitting the two PCBs, it is found through observation that the 30W gallium nitride charger of Orange Fruit Electronics uses a Biyi micro KP22062A encapsulated gallium nitride chip and a KP40612 synchronous rectifier chip to form a wide-range output flyback switching power supply, and the output voltage is adjusted by the SW2301 protocol chip of Zhirong Technology through optocoupler feedback.
The bottom board is for power input and secondary synchronous rectification and protocol, solder fuse, NTC thermistor, SMD Y capacitor, secondary solder filter solid state capacitor and USB-C receptacle.
The back of the small board is welded with a rectifier bridge, feedback optocoupler, synchronous rectifier chip and protocol chip.
The side plates are welded with high-voltage filter capacitors, differential mode inductors and transformers.
On the other side, the GaN chip is soldered and sealed, and we will start from the input to understand the information of each component.
Solder the chip fuse on the front of the PCBA module, the specification is 3.15A 250V.
The NTC thermistor is derived from Shiheng Electronics, silk-screened 3D5, and is used to suppress the inrush current at power-up.
The rectifier bridge is soldered on the back of the PCBA module, model FMB30M, specification is 3A 1000V.
The side of the PCB is welded with high-voltage filter capacitors and differential mode inductors.
The two high-voltage filter capacitors are from Yide, and the specification is 27μF 400V.
Differential mode inductor jacket heat shrink tube insulation.
The encapsulated GaN chip is from Biyi Micro, model KP22062A, and has an integrated 650V 360mΩ GaN switch tube. The chip has an integrated drive adjustment function that adjusts the drive speed when the switch is turned on to optimize the EMI performance of the system. The KP22062 operates at frequencies up to 500kHz and can operate in quasi-resonant mode over the full range.
The chip supports ultra-wide VDD power supply range of 9V-112V and supports 140/300/500kHz switching frequency. The chip directly detects the AC input voltage, supports the fast start function, the X-capacitor discharge function and the standby power consumption of less than 30mW, meets the requirements of Level 6 energy consumption, and integrates comprehensive protection functions.
