The MX6676DH from HCW-HENGCHENGWEI is a high-efficiency 700V GaN integrated AC-DC power IC designed for compact, high-performance power supply applications. Built with advanced Gallium Nitride (GaN) technology, this device supports fast switching at 105KHz, significantly reducing switching losses while enabling higher power density and improved system efficiency. Its low RDS(on) of 2500mΩ minimizes conduction losses, resulting in superior thermal performance and long-term operational reliability.
With a robust 700V voltage rating, the MX6676DH provides a clear advantage over lower voltage alternatives by offering enhanced safety margins and improved tolerance to voltage surges and fluctuations. This makes it ideal for wide-range AC input environments and demanding power conditions. The IC integrates key control and power functions, reducing the need for external components and simplifying overall circuit design.
Encapsulated in a compact DFN 6×8 package, the MX6676DH delivers excellent thermal dissipation and layout flexibility, making it highly suitable for space-constrained and high-density designs. It is widely used in AC-DC adapters, LED drivers, smart home devices, industrial auxiliary supplies, and consumer electronics. Combining efficiency, compactness, and reliability, the MX6676DH is a strong solution for modern power conversion systems.
