It takes a supply from 10.8 V to 17 V and draws only 150 µA during startup, making it a fit for industrial and telecom power supplies where the PFC stage needs to stay efficient at light load. The 16-TSSOP package keeps the board footprint small — handy when you are retrofitting a PFC stage into an existing power-board layout. ## Temperature grade and where it goes Rated from -40°C to 85°C, this part covers factory-floor power supplies, outdoor telecom rectifiers in cabinets, and server PSUs that see ambient heat but not engine-bay extremes. It is not AEC-Q100 qualified, so keep it out of under-hood automotive designs. For a motor-drive PFC stage inside a ventilated enclosure, the 85°C ceiling is fine as long as the local ambient near the controller stays below that. ## Tube vs reel — the packaging difference The UCC2819APW ships in a tube, suitable for prototype runs or rework bench hand-placing. For pick-and-place lines, order the tape-and-reel variant. ## Active and available — no LTB clock ticking This part carries an Active lifecycle status, so there is no last-time-buy deadline to manage. You can qualify it into a new design without worrying about a sudden EOL notice next quarter. ROHS3 compliant, no lead-free transition issues.","metaTitle":"UCC2819APW PFC Controller, Average Current, 250kHz, 16-TSSOP","metaDescription":"UCC2819APW PFC controller from Texas Instruments.

The silicon, the 16-TSSOP package, the electrical specs, and the temperature range are identical. Choose the tube version for bench work or low-volume assembly; choose the reel version for automated pick-and-place lines."},{"question":"What is the UCC2819APW operating frequency?","answer":"The switching frequency is 250 kHz. That sets the boost inductor value and the compensation network — if you are replacing a PFC controller that ran at a different frequency, plan to recalculate those external components."},{"question":"UCC2819APW equivalent part?","answer":"Within the same family, the UCC2819APWR is the tape-and-reel equivalent of this tube-shipped part — same function, same footprint. For a functional equivalent from another manufacturer, look for an average-current-mode PFC controller in a 16-TSSOP package switching near 250 kHz with a 10.8 V to 17 V supply range. Pin compatibility varies, so verify the pinout against your layout before ordering an alternate."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/UCC2819APW","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/UCC2819APW when reusing this data.
