The MX9320A from HCW-HENGCHENGWEI is a high-efficiency 700V GaN integrated AC-DC power IC engineered for modern compact power supply designs. Leveraging advanced Gallium Nitride (GaN) technology, this device delivers fast switching performance at 105KHz, significantly reducing switching losses while enabling higher power density. Its low RDS(on) of 2500mΩ minimizes conduction losses, ensuring improved efficiency and superior thermal performance compared to conventional silicon-based solutions.
Designed for high-voltage applications, the 700V rating provides greater reliability and safety margin over lower voltage series, making it suitable for unstable or wide-range AC input environments. The MX9320A integrates essential power control functions, reducing external component count and simplifying circuit design, which helps lower overall system cost and improves reliability.
Housed in a compact HSOP7 package, this IC offers excellent layout flexibility for space-constrained applications. Its efficient heat dissipation and stable operation make it ideal for long-term use in demanding conditions. The MX9320A is widely used in AC-DC adapters, LED drivers, smart home power modules, industrial auxiliary supplies, and various consumer electronics, delivering consistent performance, high efficiency, and compact design advantages.
