The MX7710B from HCW-HENGCHENGWEI is a high-efficiency 700V GaN synchronous rectifier (SR) IC engineered to enhance performance in modern AC-DC power conversion systems. Utilizing advanced Gallium Nitride (GaN) technology, this device supports ultra-fast switching at 105KHz, significantly reducing switching losses compared to traditional rectification methods. By replacing conventional Schottky diodes, it achieves a lower forward voltage drop (low VF), minimizing power dissipation and improving overall system efficiency.
With a robust 700V voltage rating, the MX7710B provides superior reliability and increased safety margins over lower voltage SR devices, making it ideal for wide-range AC input applications and unstable power environments. Its low RDS(on) of 2500mΩ reduces conduction losses, ensuring excellent thermal performance and long-term operational stability.
Encased in a compact SOP-8 package, the MX7710B offers flexible PCB layout options and efficient heat dissipation, making it suitable for space-constrained and high-density designs. It is widely used in high-efficiency AC-DC adapters, fast chargers, LED drivers, industrial power supplies, and consumer electronics. Combining GaN fast-switching advantages, low VF characteristics, and compact integration, the MX7710B is a reliable solution for next-generation synchronous rectification applications.
