SC3806 Overview
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.
SC3806 Key Features
- Internally synchronized PFC and PWM
- Slew rate enhanced voltage error
- 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
- SOP16 and DIP-16 package
