It operates at a 200 kHz switching frequency and accepts a supply voltage from 10V to 20V, with a low 250 µA startup current. The part is rated for the industrial temperature range of -40°C to 85°C, making it suitable for outdoor telecom rectifiers, motor-drive auxiliary supplies, and factory-automation power stages where PFC is required to meet harmonic-current limits. ## Supply range and startup current — bias design The 10V to 20V supply range covers the output of a standard auxiliary winding or a regulated bias rail. The 250 µA startup current is low enough that a high-value startup resistor can charge the VCC capacitor without excessive dissipation. ## Lifecycle — active, no LTB risk The UC2854ADW is listed as Active with ROHS3 compliance.","metaTitle":"UC2854ADW PFC Controller, Average Current Mode, 200kHz","metaDescription":"UC2854ADW average current mode PFC controller from TI. 200kHz switching, 10V-20V supply, 250µA startup, -40°C to 85°C, 16-SOIC.

Within the same TI family, the UC3854 series is a functional equivalent with similar pinout and control architecture — verify the specific variant's supply range and switching frequency against your design's requirements before substituting."},{"question":"Does UC2854ADW require an external MOSFET?","answer":"Yes, the UC2854ADW is a controller IC and requires an external MOSFET and boost diode to form the complete PFC stage. The gate-drive output is designed to drive a standard power MOSFET through a series resistor."},{"question":"What is the difference between UC2854 and UC3854?","answer":"Both are average current mode PFC controllers from TI. The UC2854 is specified for the industrial temperature range (-40°C to 85°C), while the UC3854 is typically rated for commercial temperature (0°C to 70°C). The UC2854ADW is the 16-SOIC surface-mount variant of the UC2854 family."},{"question":"What is UC2854ADW's listed mode (Average Current) on this component line?","answer":"The UC2854ADW operates in Average Current mode, which provides continuous inductor current sensing and low total harmonic distortion (THD) over a wide load range — the preferred control method for active PFC stages above 75W."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/UC2854ADW","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/UC2854ADW when reusing this data.
