Texas Instruments XUCC28056DBV

UCC28056 is a fully featured PFC controller offering excellent light load efficiency and standby power. UCC28056 simplifies the design of power supply system’s requiring good power factor, that must also be capable of meeting today’s tough standards for efficiency and standby power. At full load, UCC28056 operates the PFC power stage at maximum switching frequency in Transition Mode. At reduced load, the part transitions seamlessly into Discontinuous Conduction mode, automatically reducing switching frequency for maximum efficiency. At light load, DCM operation is combined with Burst Mode operation to further improve light load efficiency and standby power. UCC28056 integrates all the features necessary to implement a high performance and robust PFC stage into a 6-pin package and requires a minimal number of external components to interface with the power stage.
