The UCC28019AEVM is an evaluation module for UCC28019A continuous conduction mode (CCM) PFC controller. The UCC28019A is a 8 pin active power factor correction (PFC) controller uses the boost topology operating in CCM mode. This controller is suitable for systems in the 100W to 2KW range over a wide range universal ac line input. The UCC28019AEVM is 350W off line power factor correction boost converter providing a 390V regulated output at 0.9A of load current. The power factor correction converter accommodates an input voltage range of 85Vac to 265Vac and uses average current mode control at a fixed frequency of 65KHz. The evaluation module highlights the many benefits of using the UCC28019A continuous current mode PFC controller. The controller operates under average current mode control at a fixed frequency of 65KHz. Simple external current and voltage loop compensation, along with advanced protection features.
