UCC28056CDBVR Integrated Circuit Chip High Performance Single-Phase Transition-Mode PFC Controller

UCC28056CDBVR Integrated Circuit Chip High Performance Single-Phase Transition-Mode PFC Controller

Product Description Of UCC28056CDBVR
UCC28056CDBVR device drives PFC boost stages based on an innovative mixed mode method that operates in transition mode (TM) at full load and transitions seamlessly into discontinuous conduction mode (DCM) at reduced load, automatically reducing switching frequency. This device incorporates burst mode operation to further improve light load performance, enabling systems to meet challenging energy standards while eliminating the need to switch off the PFC. UCC28056CDBVR can drive a PFC power stage up to 300 W, ensuring sinusoidal line input current with low distortion, close to unity power factor.
