This is a breakout board for UCC28019 and UCC28128 PFC controllers. This module enables users to build a high-power PFC (Power Factor Correction) controller. Active PFC 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. The startup current during an 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.
Note 1: The PFC controller module is published here. The second part (mainboard) is 350W Power Factor Boost Converter for Inverter-Fed BLDC and PMSM Motors.
Note 2: This module can accommodate two chips UCC28019 or UCC28180. Refer to the datasheet of both chips to select the components as per requirements.
