Gallium nitride is a representative of high conversion efficiency wide bandgap semiconductor materials. Fast charging solutions developed based on gallium nitride power devices use highly integrated gallium nitride power chips to obtain streamlined peripheral circuits and only need to be equipped with a few low-power devices. A solution can be formed by pressing MOS and VBUS switch tubes, which can effectively reduce the PCB board area and motherboard temperature, effectively increase the power density, and enable the LCD TV to achieve a thinner design and lower R&D costs.
