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.
Yes, the UCC28056BDBVR is ROHS3 compliant, meeting the latest EU RoHS directive without exemptions.
The startup current is 46 µA, which allows a small VCC capacitor and fast start-up with minimal standby loss.
