SG6905
Overview
The highly integrated SG6905 is specially designed for power supplies consisting of boost PFC and flyback PWM. It requires very few external components to achieve green-mode operation and versatile protections.
- Interleaved PFC/PWM Switching
- Green Mode PWM Operation
- Low Startup and Operating Current
- Innovative Switching-Charge Multiplier-Divider
- Average-Current-Mode Control for PFC
- PFC Over-Voltage and Under-Voltage Protections
- PFC Remote On/Off Control
- PFC and PWM Feedback Open-Loop Protection
- Cycle-by-Cycle Current Limiting for PFC/PWM
- Slope Compensation for PWM
