What is the GaN charger?

The chemical name of Gallium nitride is GaN, The GaN charger is a new technology on charging devices. The GaN chargers made of gallium nitride materials with more higher power and smaller sizes, The sizes are smaller for the same amount of power, and more power for the same sizes. In short, Gallium nitride is the core materials of the third generation semiconductor. GaN chargers description: The new technologies on GaN Chargers are expected to improve greatly on many aspects as power management, power generation and power output,etc. It has the characteristics of large band gap width, high thermal conductivity, high temperature resistance, radiation resistance, acid and alkali resistance, high strength and high hardness. Gallium nitride is new semiconductor materials which can replace silicon and germanium, The frequency of switch tube made of GaN materials is greatly improved, but the loss is less, This allows chargers to use smaller transformers and other inductance components, thus increasing efficiency. GaN has better breakdown ability, higher electron density and electron mobility, also higher working temperature than silicon based semiconductor .

The TWS headphones has grew by 17% percent in the Q1 of 2022 from global market

The global market for true wireless headsets (TWS) has grew by 17 percent and reach to 68.2 million units in the first quarter of 2022, according to the new data released by Canalys reported on JUN 06, 2022. Apple, Xiaomi and Samsung still remained the top three ranks in this quarter, but only Apple has posted growth.   TWS headphones was the only device category to grow since the third quarter of 2021, leading the overall growth of 4% in personal smart audio devices in the worldwide.  Apple, the market leader, saw shipments of its AirPods series, rising 14 percent and reach to 19.3m units, while Beats by Dre, its audio device brand, saw even more impressive growth, rising 553 percent and reach to 2.4m units.   Beats' strong performance was helped by a strong reception for the Studio Buds headphones and its recently launched Fit Pro headphones.  According to consumer’s requirements, it is hard to launch a generation of TWS headphones per year, This category was extremely competitive, The third-party vendors to sell goods in the margins of society, The company hope to sell a phone with a TWS headphones together. General in all, TWS headphones will continue to maintain growth in the next few quarters, but will be more competitive.

The difference between PD charging cable and normal charging cable

Charging speed PD charging cable is integrated with quasi-resonant current mode controller and power MOSFET built in, which has the characteristics of high performance, low standby power consumption and low cost. But for the normal charging cable, The specification is 5V2A with constant current and voltage charging mode, the charging speed is slow. Current switching after charging is over The chip inside the PD charging cable can control the charging process, it will stop automatically once the charging is full, making the whole charging process more safe and efficient.   As for the normal cables with 5V2A, When the battery is full, it automatically changes to trickle charging state. For PD charging cables, the best efficiency under the full voltage range is achieved by using the mixed modulation technology of QR-PWM, QR-PFM and burst-mode and the low-power structure technology of special devices.   At the same time, it provides comprehensive and excellent performance of intelligent protection functions, including output overvoltage protection, periodic overcurrent protection, overload protection, soft start function.  The normal charging cables with less components and simple designs, there are internal integration of 650V intelligent power MOSFET with high avalanche capacity built in, The circuit design is simple and easy to implement also the price is low. Please choose to buy from the reputable retailer.
