    The SC3201 is a Power Factor Correction (PFC) controller
    which is applied to boost converter. It features High
    performance by using multi-mode control strategy. At heavy
    load or full load, it operates in Critical conduction Mode
    (CrM). When load decreases, it operates in Discontinuous
    Conduction Mode (DCM) with valley switching and lower
    frequency for high efficiency. And at no load, the IC will
    operate in Burst Mode to reduce power consumption and
    minimize audio noise. Using SC3201 together with the
    Flyback controller and secondary synchronous rectifier
    controller, high efficiency over full load can be achieved, and
    extremely low standby power consumption of system can
    easily meet the efficiency regulations.
    Benefit from the SC3201    ，the PFC stage will obtain nearly
    unity power factor and sinusoidal line input current with few
    external components.
    SC3201 offers comprehensive protections to prevent the
    circuit from damage under abnormal conditions.
    SOT23-6 package is provided to simplified user’s design
    and reduced system cost
