UCC28019 - Texas Instruments

UCC28019 PFC Controller

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 200 µA. The user can control low power standby mode by.
