Description
The SC3806 is a controller for power factor correction, switched mode power supplies.
Internally synchronized leading-edge PFC and trailing-edge PWM in one IC.
Its input current shaping is close to the leading edge modulation average current topology.
Features
- Internally synchronized PFC and PWM.
- Slew rate enhanced voltage error
amplifier with advanced input current shaping technique.
- Average current, continuous boost leading edge PFC.
- PFC using Input Current Shaping Technique.
- High PF with low total harmonic distortion.
- Reduced ripple current in bulk capacitor between PFC and PWM sections.
- Current-fed gain modulator for improved noise immunity.
- Overvoltage and brown-out protection, UVLO, and soft start.
- S.
