SG6901A
Overview
The highly integrated SG6901A is designed for power supplies with boost PFC and flyback PWM. It requires Product Specification SG6901A very few external components to achieve versatile protections.
- Interleaved PFC/PWM switching
- Low start-up and operating current
- Innovative switching charge multiplier-divider
- Multi-vector control for improved PFC output transient response
- Average-current-mode control for PFC
- Programmable two-level PFC output voltage
- PFC over-voltage and under-voltage protections
- PFC and PWM feedback open-loop protection
- Cycle-by-cycle current limiting for PFC/PWM
- Slope compensation for PWM
