The MX7709C from HCW-HENGCHENGWEI is a high-efficiency 700V GaN synchronous rectifier (SR) IC designed for compact and high-performance AC-DC power conversion systems. Built with advanced Gallium Nitride (GaN) technology, this device delivers ultra-fast switching at 105KHz, significantly reducing switching losses compared to conventional rectification methods. By replacing traditional Schottky diodes, it achieves a lower forward voltage drop (low VF), minimizing energy loss and improving overall system efficiency.
With a robust 700V voltage rating, the MX7709C provides enhanced reliability and higher safety margins over 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 a compact PDFN 5×6 package, the MX7709C offers superior heat dissipation and flexible PCB layout options, making it well-suited for space-constrained and high-density designs. The integrated architecture reduces external component count, simplifying circuit design and improving overall system reliability. It 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 MX7709C is an ideal solution for next-generation synchronous rectification applications.
