What is GaN and How Does it Change the Power Supply Industry?
Gallium Nitride (GaN) is a revolutionary semiconductor material that’s transforming the power supply industry as it offers significant advantages in terms of efficiency, size, and weight compared to traditional silicon-based transistors.
GaN power sources have a wider bandgap, which allows them to handle higher voltages and temperatures while operating at higher frequencies. This translates to increased power density, meaning you can pack more power into a smaller space to create a compact design. Additionally, GaN’s lower on-state resistance and faster switching speeds lead to significantly higher efficiency, as well as superior heat dissipation properties, reducing power loss and minimizing the need for bulky cooling components. In turn, GaN power supply units (PSU) contribute to lower overall system costs.
By incorporating GaN into our product lineup, Phihong offers a range of smaller, lighter, and more efficient power solutions for various applications, from portable electronics to high-performance computing.

How to Select the Right GaN Power Supply?
An incompatible power supply may not provide sufficient power to charge your devices quickly, and may even lead to overloading and damage to your device. So, carefully consider the following factors to make sure you select a GaN power supply that meets your specific requirements:
- Safety Certifications: Look for power supplies that have undergone rigorous safety testing and certifications, such as UL, CE, and RoHS, which can help guarantee the product’s safety and reliability.
- Power Requirements: Assess the maximum power output required for your devices to determine if the GaN power supply can deliver sufficient wattage for efficient charging. Avoid choosing GaN PSUs with wattage higher than what your device can take as it would lead to overloading.
- Fast Charging Protocol: GaN PSUs support various fast charging protocols, including Power Delivery (PD), Quick Charge (QC), etc. While this is compatible with most devices, it is still important to ensure that your devices support this feature.
- Size and Weight: If the GaN power adapter has to be carried around, you may consider compact and lightweight models, but make sure to balance size and power so that you don’t compromise performance.
- Number of Devices to Charge: Some users may have to charge multiple devices simultaneously. In this case, choose a power supply with enough ports to accommodate your needs and check how the power is distributed among the ports to ensure the devices are charged efficiently.
- Switching Circuit Design: This GaN power supply feature determines its switching frequencies and on-state resistance, so choose a circuit design that fits the power output, efficiency rates, and cost requirements of your specific application.
Why Should You Consider the GaN Driver Capabilities of the Power Supply?
The GaN driver plays a crucial role in bridging the gap between the low-voltage control signals from the main power supply unit and the high-voltage, high-current demands of the GaN transistor. It acts as an intermediary, translating the control signals into appropriate gate drive signals that can effectively control the switching behavior of the GaN transistor.
In essence, the GaN driver is a critical component that directly impacts the performance and efficiency of a GaN power supply. Choosing a power supply with a high-quality GaN driver can ensure optimal operation and long-lasting durability.
