The HC7717A is a high-efficiency 45V GaN integrated circuit from HCW-HENGCHENGWEI, designed for compact and efficient power conversion systems up to 20W. Built on advanced Gallium Nitride (GaN) technology, this device delivers fast switching performance, reduced switching losses, and improved overall efficiency compared to traditional silicon-based solutions. With a low 20mΩ RDS(on), the HC7717A minimizes conduction losses, ensuring stable thermal performance and reliable operation under continuous load conditions.
This device is optimized for high-frequency operation and supports “搭配高频副边同步” (high-frequency secondary-side synchronous operation), enabling improved system efficiency and better output regulation in modern power supply designs. By reducing energy losses and improving conversion efficiency, it helps achieve compact, high power-density solutions.
The 45V voltage rating makes it suitable for low-voltage DC-DC conversion and battery-powered applications, while the SOP-6 package ensures compact PCB footprint and flexible integration in space-constrained designs. Its efficient thermal characteristics support stable long-term operation in demanding environments.
The HC7717A is an ideal solution for designers seeking a balance of efficiency, compact size, and synchronized high-frequency performance in GaN-based power systems.
