General Descriptions
The SSC2000 series products are power factor correction (PFC) controller ICs of Continuous Conduction Mode (CCM). The product achieves high power CCM systems, with few external components and no multiplier by the average current control method.

Features
● Continuous Conduction Mode (CCM)
    The mode enables the low peak current recommended for high power supplies.
● Average Current Control Method
    The method requires no input line voltage sensing and no multiplier, and achieves simple systems with few external components.
● Pulse Width Modulation (PWM) + Frequency Modulation Function
    The function superposes the modulated frequency according to Duty value, on the internally fixed PWM frequency of 65 kHz(TYP).
● Maximum Duty Cycle : 94% (TYP)
● Built-in High Speed Response for Dynamic Load Changes
● Error Amplifier Reference Voltage : 3.5V (TYP)
● Brown-In / Brown-Out Function
    The function enables the oscillation start/stop by externally rated input voltage and makes protections at low input voltage.
● Various Protections
    Overvoltage Protection (OVP) -------------------------------- Auto-Restart
    VCC Undervoltage Lockout (UVLO) -------------------------- Auto-Restart
    Overcurrent Protection (OCP) -------------------------------- Auto-Restart
        Two Overcurrent Detection Thresholds : Input Current Limitation (OCPL)
                                                                         Peak Current Limitation (OCPH)
    Output Open Loop Detection (OLD)-------------------------- Auto-Restart

Applications
