The UCC28019A 8-pin active power factor correction (PFC) controller operates in a continuous conduction mode (CCM) boost topology. The controller is suitable for use in a wide range of universal AC line inputs to a range of 2 kW in a 100 watt system. During start-up, the undervoltage lockout current is less than 200 microamps. The user can control the pin of 0.77 or less to pull VSENSE in low-power standby mode five
Low distortion wave input average current mode control current shaping is inseparable from input line voltage sensing, reducing the number of external components. A simple external network allows flexible compensation of current and voltage control loops. Its switching frequency is internally fixed and trimmed by 25 to better than ± 5% accuracy°C
characteristic
- The 8-pin solution reduces external components
- Wide universal AC input voltage range
- Fixed 65 kHz operating frequency
- Maximum duty cycle of 98% (typical)
- Output over/under voltage protection
- Input undervoltage protection
- Cycle-by-cycle peak current limit
- Open-loop detection
- A low-power standby mode controls the user
-
