The MX7716B from HCW-HENGCHENGWEI is a high-efficiency 700V GaN synchronous rectifier (SR) IC engineered to improve performance 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 rectification. By replacing conventional Schottky diodes, it achieves a lower forward voltage drop (low VF), minimizing power dissipation and enhancing overall system efficiency.
With a robust 700V voltage rating, the MX7716B provides superior reliability and higher 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 reduces conduction losses, ensuring excellent thermal performance and long-term operational stability.
Encased in an ESOP-8 package, the MX7716B offers efficient heat dissipation and flexible PCB layout options, making it suitable for compact and high-density designs. The integrated architecture reduces external component requirements, simplifying circuit design and improving overall system reliability. This IC is widely used in high-efficiency AC-DC adapters, fast chargers, LED drivers, industrial power supplies, and consumer electronics.
Combining GaN fast-switching capability, low VF benefits, and compact integration, the MX7716B is an ideal solution for next-generation synchronous rectification applications.
