Product details

Average current mode PFC controller in a 16-TSSOP

The Texas Instruments UCC2819APW is a power-factor-correction controller operating in average current mode, switching at 250 kHz. 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.

Temperature grade and where it goes

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

ROHS3 compliant, no lead-free transition issues.

Frequently asked questions

What is the difference between UCC2819APW and UCC2819APWR?

The only difference is the shipping medium: UCC2819APW comes in a tube, while UCC2819APWR comes in tape and reel. 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.

What is the UCC2819APW operating frequency?

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.

UCC2819APW equivalent part?

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.
