POWER
VOLTAGE
Gallium Nitride (GaN) is a next-generation semiconductor material that enables chargers to deliver more power with greater efficiency than traditional silicon-based designs. By switching at higher frequencies and generating less heat, GaN technology allows OEMs to develop smaller, lighter, and more reliable USB-C PD chargers without compromising performance.
Whether you’re designing a compact consumer charger or an embedded power solution for commercial devices, GaN technology provides significant advantages in size, thermal performance, and energy efficiency.
GaN transistors operate more efficiently than conventional silicon MOSFETs, allowing more power to be delivered from a significantly smaller PCB. This enables compact charger designs while maintaining high output performance.
Because less heat is generated, GaN chargers require smaller magnetic components and reduced cooling space. The result is a lighter, more compact charger that is easier to integrate into modern products.
High conversion efficiency reduces energy loss during charging, lowering operating temperatures and improving long-term reliability while helping meet global energy efficiency regulations.
Lower switching losses generate less heat, allowing chargers to operate more reliably under continuous high-power conditions and extending component lifespan.
GaN technology makes it practical to deliver 65W, 100W, 140W, and even 240W USB-C PD charging in compact form factors that would be difficult to achieve using traditional silicon technology.
Modern USB-C chargers need to support multiple fast charging standards to ensure compatibility across different devices and brands. Our OEM USB-C PD chargers can be configured to support a wide range of charging protocols, enabling reliable fast charging for laptops, tablets, smartphones, portable displays, industrial terminals, and embedded systems.
Protocol support may vary depending on the charger model and project requirements.
USB Power Delivery is the industry-standard fast charging protocol based on USB Type-C. It intelligently negotiates voltage and current between the charger and connected device, delivering only the power required for safe and efficient charging. PD 3.1 extends the maximum power delivery up to 240W, making it suitable for high-performance laptops, workstations, portable monitors, and professional equipment.
PPS allows the charger to adjust output voltage in fine increments rather than fixed voltage levels. This improves charging efficiency, reduces heat generation inside mobile devices, and is widely adopted by modern Android smartphones.
Quick Charge remains one of the most widely used fast charging standards for Android devices. Supporting QC compatibility helps maximize interoperability with existing smartphones and embedded handheld terminals.
For broader compatibility, chargers can also support traditional USB charging standards used by many legacy devices, ensuring stable charging across a wider range of products.
