The MX77068AS from HCW-HENGCHENGWEI is a high-efficiency 700V GaN synchronous rectifier (SR) IC engineered for advanced AC-DC power conversion systems. Leveraging cutting-edge Gallium Nitride (GaN) technology, this device delivers ultra-fast switching performance at 105KHz, significantly reducing switching losses compared to conventional rectification methods. By effectively replacing traditional 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 MX77068AS provides enhanced reliability and greater safety margins over lower voltage SR solutions, making it well-suited for wide-range AC input applications and unstable power environments. Its low RDS(on) of 2500mΩ reduces conduction losses, ensuring excellent thermal performance and extended operational lifespan.
Packaged in a compact SOP-8 form factor, the MX77068AS offers flexible PCB layout and efficient heat dissipation, ideal for high-density and space-constrained designs. It is widely used in high-efficiency AC-DC adapters, fast chargers, LED drivers, industrial power supplies, and consumer electronics. Combining GaN-based fast switching, low VF advantages, and compact integration, the MX77068AS is a reliable solution for next-generation synchronous rectification designs.
