Description of product

UCC28056 High Performance PFC Controllers

Texas Instruments UCC28056 6-Pin High-Performance PFC Controllers offer an innovative mixed-mode method derived from the devices’ PFC boost stages. The mixed-mode method operates in Transition Mode (TM) at full load and transitions smoothly into Discontinuous Conduction Mode (DCM) at a reduced load, resulting in automatically decreasing switching frequency. Improving light load performance, the device includes burst mode operation eliminating the need to switch off the PFC allowing systems to meet demanding energy standards. Additionally, the UCC28056 ensures sinusoidal line input current with low distortion, while the PFC stays on via the PFC power stage driving up power to 300W. Combined with the UCC256301 LLC controller, the need for an auxiliary flyback converter is eliminated. The UCC28056 provides an instant turn-on feature and lessens the external component count to a minimum.
