It integrates control logic and gate drive for a single-switch PFC stage. ## Package and temperature grade Housed in a 6-pin SOT-23 package (SOT-23-6), the part is a surface-mount device suited for automated assembly on dense PCBs. The -40°C to 125°C operating temperature range covers industrial ambient conditions and the self-heating inside a sealed power supply enclosure. ROHS3 compliance is confirmed, so no exemption declarations are needed for EU or similar markets. ## Sourcing and lifecycle No direct replacement or second-source alternate is listed on the record; the part is sourced through independent distribution and quoted to order against an RFQ.","metaTitle":"UCC28056BDBVR PFC Controller, Discontinuous Mode, SOT-23-6","metaDescription":"UCC28056BDBVR PFC controller from TI.
