UCC28019DR

8针连续传导模式（CCM ） PFC控制器 8-Pin Continuous Conduction Mode CCM PFC Controller

DESCRIPON

The UCC28019 8-pin active Power Factor Correction PFC controller uses the boost topology operating in Continuous Conduction Mode CCM. The controller is suitable for systems in the 100 W to >2 kW range over a wide-range universal ac line input. Startup current during under-voltage lockout is less than 200µA. The user can control low power standby mode by pulling the VSENSE pin below 0.77 V.
