FAN7930C,Critical Conduction Mode (CRM) PFC Controller,8-SOP

The FAN7930C is a high-performance Critical Conduction Mode (CRM) Power Factor Correction (PFC) Controller designed for boost PFC applications in adapters, ballasts, and TV power supplies. It offers low power loss and high efficiency by operating in CRM and features advanced protection mechanisms such as OVP, OCP, and UVLO for enhanced reliability.

Its built-in PFC-ready signal enables seamless interaction with other power stages, while the THD optimizer ensures excellent power factor correction with minimal harmonic distortion. With an 8-SOP package, the FAN7930C is compact and easy to integrate into modern electronic designs.

• Critical Conduction Mode (CRM): Optimized for boost PFC applications, reducing power losses and improving efficiency.
