Description
General part information
UCC28019A Series
The UCC28019A 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. Start-up current during undervoltage 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 external 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 peak gate current drives the external switch.
Numerous system-level protection features include peak current limit, soft over-current, open-loop detection, input brown-out, and output over/undervoltage. Soft-start limits boost current during start-up. A trimmed internal reference provides accurate protection thresholds and a regulation set-point. An internal clamp limits the gate drive voltage to 12.5 V.
