Product Overview

The UCC28019AD is a 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 >2kW range over a wide-range universal ac line input. Start-up current during undervoltage lockout is less than 200µA. The user can control low power standby mode by pulling the VSENSE pin below 0.77V. 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 1.5A 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.
  • Wide-range universal AC input voltage
  • Output over/undervoltage protection
  • Input brown-out protection
  • Cycle-by-cycle peak current limiting
  • Open loop detection
  • Low-power user-controlled standby mode
  • Green product and no Sb/Br
