MX77065B SR Controller IC 65V 10mΩ SOP-8 | Efficient SR IC | HCW-HENGCHENGWEI

HCW-HENGCHENGWEI

The HCW-HENGCHENGWEI GaN AC-DC integrated IC and synchronous rectifier (SR) controller series deliver a complete high-efficiency power conversion solution for modern fast charging and compact power supply applications. Built using advanced Gallium Nitride (GaN) technology, the primary-side ICs provide superior switching performance, reduced switching losses, and higher power density compared to traditional silicon-based designs.

The GaN IC series supports power levels from 20W to 65W, with compact package options such as HSOP-7, ESOP-8, and DFN6x8, enabling ultra-compact adapter designs. These devices operate at high switching frequencies, allowing smaller magnetic components, improved thermal efficiency, and optimized system reliability.

Complementing the primary side, the synchronous rectifier controller series offers voltage ratings from 40V to 120V with ultra-low RDS(on) down to 7mΩ, significantly reducing conduction losses on the secondary side. This results in improved overall efficiency, lower heat generation, and enhanced performance in flyback and QR power architectures.

With features such as multi-mode compatibility, high efficiency, compact packaging, and reduced external component requirements, this GaN + SR solution is ideal for high-performance power systems.
