Description for the UCC28019

The UCC28019 8-pin active Power Factor Correction (PFC) controller uses the boost topology operating in Continuous Conduction Mode (CCM). The controller is suitable for systems in the 100 W to >2 kW range over a wide-range universal ac line input. Startup current during under-voltage lockout is less than 200 µA. The user can control low power standby mode by pulling the VSENSE pin below 0.77 V.

Low-distortion wave-shaping of the input current using average current mode control is achieved without input line sensing, reducing the Bill of Materials component count. Simple external networks allow for flexible compensation of the current and voltage control loops. The switching frequency is internally fixed and trimmed to better than 5% accuracy at 25°C. Fast 1.5-A gate peak current drives the external switch.

Numerous system-level protection features include peak current limit, soft over-current detection, open-loop detection, input brown-out detection, output over-voltage protection/under-voltage detection, a no-power discharge path on VCOMP, and overload protection on ICOMP. Soft-Start limits boost current during start-up. A trimmed internal reference provides accurate protection thresholds and regulation set-point. An internal clamp limits the gate drive voltage to 12.5 V.

Carrier options

You can choose different carrier options based on the quantity of parts, including full reel, custom reel, cut tape, tube or tray.

A custom reel is a continuous length of cut tape from one reel to maintain lot- and date-code traceability, built to the exact quantity requested. Following industry standards, a brass shim connects an 18-inch leader and trailer on both sides of the cut tape for direct feeding into automated assembly machines. TI includes a reeling fee for custom reel orders.

Cut tape is a length of tape cut from a reel. TI may fulfill orders using multiple strips of cut tapes or boxes to satisfy the quantity requested.

TI often ships tube or tray devices inside a box or in the tube or tray, depending on inventory availability. We pack all tapes, tubes or sample boxes according to internal electrostatic discharge and moisture-sensitivity-level protection requirements.
