UCC28180
Description
The UCC28180 is a flexible and easy-to-use, 8-pin, active Power-Factor Correction (PFC) controller that operates under Continuous Conduction Mode (CCM) to achieve high Power Factor, low current distortion and excellent voltage regulation of boost preregulators in AC - DC front-ends.
Key Features
- 1 8-Pin Solution (No AC Line Sensing Needed)
- Wide Range Programmable Switching Frequency (18 kHz to 250 kHz for MOSFET and IGBT-based PFC Converters)
- Trimmed Current Loop Circuits for Low iTHD
- Reduced Current Sense Threshold (Minimizes Power Dissipation in Shunt)
- Average Current-Mode Control
- Soft Over Current and Cycle-by-Cycle Peak Current Limit Protection
- Output Overvoltage Protection With Hysteresis Recovery
- Audible Noise Minimization Circuitry
- Open Loop Detection
- Enhance Dynamic Response During Output Overvoltage and Undervoltage Conditions
