MX7714C Synchronous Rectifier IC 40V 15m? ESOP-8 | CCM/DCM/QR Compatible SR Controller | HCW-HENGCHENGWEI

The HCW-HENGCHENGWEI GaN power IC and synchronous rectification (SR) series are engineered for high-efficiency AC-DC and DC-DC power conversion systems, supporting multiple operating modes including CCM (Continuous Conduction Mode), DCM (Discontinuous Conduction Mode), and QR (Quasi-Resonant Mode). These devices are optimized for modern fast charging adapters, high-frequency switching power supplies, and compact high-density power designs.

The primary-side GaN IC series offers voltage ratings from 85V to 100V, with ultra-low RDS(on) values down to 7mΩ, significantly reducing conduction losses and improving overall efficiency. With high switching frequency support up to 500KHz, these devices enable smaller magnetic components, higher power density, and improved thermal performance compared to conventional silicon-based solutions.

The synchronous rectifier (SR) series complements the primary controllers by providing efficient secondary-side rectification with voltage ratings from 40V to 100V and ultra-low conduction resistance. This ensures reduced rectification losses, improved system efficiency, and optimized thermal management in flyback and LLC power architectures.

Available in compact packages such as SOP-8, ESOP-8, ASOP-6, and PDFN, these ICs provide flexible integration, reduced external component count, and simplified PCB design.

Together, this GaN + SR solution set is ideal for high-efficiency fast chargers, USB PD adapters, GaN power supplies, and high-frequency SMPS designs, delivering superior performance, compact size, and reliable operation across a wide range of applications.
