Transition-mode PFC controller in a SOT-23-6
The Texas Instruments UCC28056BDBVR is a PFC controller operating in Discontinuous (Transition) mode. It integrates control logic and gate drive for a single-switch PFC stage.
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. ROHS3 compliance is confirmed, so no exemption declarations are needed for EU or similar markets.
