The MX77085B from HCW-HENGCHENGWEI is a high-performance 700V GaN synchronous rectifier (SR) IC engineered to enhance efficiency in modern AC-DC power conversion systems. Utilizing advanced Gallium Nitride (GaN) technology, this device enables ultra-fast switching at 105KHz, significantly reducing switching losses compared to traditional diode rectification. By replacing conventional Schottky diodes, it achieves a lower forward voltage drop (low VF), minimizing power dissipation and improving overall system efficiency.
With a strong 700V voltage rating, the MX77085B provides superior reliability and higher safety margins compared to lower voltage SR solutions, making it ideal for wide-range AC input designs and environments with voltage fluctuations. Its low RDS(on) of 2500mΩ reduces conduction losses, ensuring improved thermal performance and long-term operational stability.
Encased in a compact SOP-8 package, the MX77085B offers excellent PCB layout flexibility and efficient heat dissipation, making it suitable for space-constrained and high-density applications. 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 benefits, and compact integration, the MX77085B is an excellent choice for next-generation synchronous rectification designs.
