The UCC28180EVM highlights the many benefits of using the UCC28180 Continuous Current Mode Boost PFC Controller (TI Literature Number SLUUAT3). The controller operates under average current mode control at a fixed programmable switching frequency of 120 kHz. Simple external current and voltage loop compensation, along with advanced protection features, make this controller ideal for server and desktop power supplies, industrial power supplies, and white goods.
