FAN4800AU
Overview
The highly integrated FAN4800AU/CU parts are specially designed for power supplies that consist of boost PFC and PWM. They require very few external components to achieve versatile protections and compensation.
- Pin-to-Pin Compatible with ML4800, FAN4800, CM6800, and CM6800A
- PWM Configurable for Current-Mode or Feed-Forward Voltage-Mode Operation
- Internally Synchronized Leading-Edge PFC and Trailing-Edge PWM in One IC
- Low Operating Current
- Innovative Switching-Charge Multiplier Divider
- Average-Current-Mode for Input-Current Shaping
- PFC Over-Voltage and Under-Voltage Protections
- PFC Feedback Open-Loop Protection
- Cycle-by-Cycle Current Limiting for PFC/PWM
- Power-on Sequence Control and Soft-Start
