UCC28019ADR - TI Function Overview

DESCRIPTION
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 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.
FEATURES
• 8-pin Solution Reduces External Components
• Wide-Range Universal AC Input Voltage
• Fixed 65-kHz Operating Frequency
• Maximum Duty Cycle of 98% (typ.)
• Output Over/Under-Voltage Protection
• Input Brown-Out Protection
• Cycle-by-Cycle Peak Current Limiting
• Open Loop Detection
• Low-Power User Controlled Standby Mode
