MX77068AN 700V 20W GaN SR IC SOP-8 | High Efficiency Synchronous Rectifier | HCW-HENGCHENGWEI

The MX77068AN from HCW-HENGCHENGWEI is a high-performance 700V GaN synchronous rectifier (SR) IC designed to enhance efficiency in modern AC-DC power conversion systems. Built using advanced Gallium Nitride (GaN) technology, this device enables ultra-fast switching at 105KHz, significantly reducing switching losses compared to traditional diode-based rectification. By replacing conventional Schottky diodes, the MX77068AN achieves lower forward voltage drop (low VF) and minimizes power dissipation, resulting in improved overall system efficiency.

With a high 700V voltage rating, the MX77068AN provides superior reliability and increased safety margins compared to lower voltage SR solutions, making it ideal for wide input AC applications and environments with voltage fluctuations. Its low RDS(on) of 2500mΩ ensures reduced conduction losses, leading to better thermal performance and extended device lifespan.

Encased in a compact SOP-8 package, the MX77068AN offers flexible PCB layout options and efficient heat management, making it suitable for space-constrained designs. This IC is widely used in high-efficiency AC-DC adapters, fast chargers, LED drivers, and industrial power supplies. Combining GaN efficiency, fast switching, and compact integration, the MX77068AN is an excellent choice for next-generation synchronous rectification solutions.
