    Everyone can get a benefits of it after use GaN charger, but do you know what is GaN? In which ways did manufacturers revolutionize the life of common chargers?

    Gallium nitride devices have faster switching speeds, lower on-state resistance (RDS-on), and smaller drive losses than traditional silicon devices. In applications requiring higher frequencies such as miniaturized power supplies, compared to traditional silicon devices It has unparalleled high conversion efficiency and low heat generation characteristics.

    Its operating speed is 20 times faster than that of traditional silicon (Si) technology, and it can achieve three times higher power. When used in cutting-edge fast charger products, it can achieve performance that far exceeds that of existing products. In this case, the output power is increased by three times.


    In the design of gallium nitride fast charging products, three core chips are mainly used, namely gallium nitride controller, gallium nitride power device and fast charging protocol controller.

    As a well-known and old-brand power chip supplier in the industry, PI has unique insights into the application of gallium nitride fast charging technology. With its own unique chip manufacturing process, the GaN power device is perfectly sealed in the main control chip, which not only improves product efficiency and guarantees stability, but also greatly reduces the threshold of power supply manufacturers’ application, which is favored by many customers.

    PowiGaN is a gallium nitride technology developed by PI itself, which can help improve system efficiency. Based on PowiGaN technology, it has developed 5 series of chip products, including InnoSwitch3-CP, EP, Pro, MX and LYTSwitch-6.

    With the characteristics of high integration, high efficiency, and high reliability, the InnoSwitch3 PowiGaN series has won unanimous praise from customers once it was launched.

    GaN transistors have higher efficiency, lower temperature, and smaller size than silicon transistor power supplies, and are the first to achieve a heat sink-free design for high-power power supplies.

    The strategy of PI company is to encapsulate and protect PowiGaN devices in IC, so as to realize the integration of controller, driver, GaN switch, protection and SR control.

    In the field of consumer power supply, PI’s InnoSwitch-3 PowiGaN power chip has been widely adopted by many well-known brands such as OPPO, ANKER, Nubia, Kyoto Tokyo-made, RAVPOWER and so on. And completed the delivery of the millionth GaN chip on September 24, 2019, enjoying a very high market share.

    The following recommends are GaN chargers that using advanced PowiGaN chips.
