Oct 03, 2022| Anker 30W gallium nitride fast charger compared to the iPhone14 charger
The gallium nitride encapsulation chip (HYC3602E) is an intelligent flyback controller with 650V voltage resistance and 450 mω GaN switch from GaN Systems. The chip uses ESOP8 heat dissipation enhanced package, which can be used for USB PD quick charge and standby power supply for TVS and monitors.
HYC3602E closed gallium nitride chip adopts intelligent digital multi-mode control, peak current control Mode, CCM Mode operation under heavy load, internal integration of GaN Systems E-mode gallium nitride power switch, overload protection period of 56mS, support frequency buffing to improve EMI performance, Adaptive gate driver balances switching loss and EMI.
HYC3602E built-in complete and rich protection functions, support transformer magnetic saturation protection, support chip power supply overvoltage protection, support overload protection, support output voltage overvoltage protection, support on-chip overheating protection, support current sampling resistor open circuit protection, standby power consumption less than 75mW, with low start current.
The electrolytic capacitors powering the gallium nitride closure chips are from Kitt and are 4.7μF 100V.
The patch Y capacitor is from Sichuan Terui Xiang Technology Co., LTD. It has the characteristics of small size and light weight, so it is very suitable for high-density power supply products such as gallium nitride fast charge. Black Shark 30W gallium nitride charger used patch Y capacitor material number TMY1102M.
Terui Xiang focuses on the R&D, production and sales of passive components, with a registered capital of 100 million yuan. There are two independent capacitor brands under TRX: SMD TRX and DIP TY capacitor. TRX will devote itself to the research of ceramic materials, so as to expand the application of more categories and provide more solutions for customers.
The protocol chip is from Zhilong, model SW2301, which is A highly integrated Type-C port /Type-A port fast charge protocol chip. It supports PD, QC, FCP, high-low voltage SCP, AFC, SFCP, PE and other mainstream fast charge protocols, and supports two working modes: optocoupler feedback and FB feedback.
The SW2301 integrates CV/CC control loops, Type-C interface logic, fast charge protocol controller, and multiple security protection features. With ACDC or DCDC and A small number of peripheral components, A complete high-performance Type-C port /Type-A port fast charging solution can be formed.
Below and to the left of the chip is a thermistor, which measures the internal temperature of the charger and protects it from overheating.
