    Power Factor Controllers
    The MC34262/MC33262 are active power factor controllers
    specifically designed for use as a preconverter in electronic ballast
    and in offline power converter applications. These integrated
    circuits feature an internal startup timer for standalone applications,
    a one quadrant multiplier for near unity power factor, zero current
    detector to ensure critical conduction operation, transconductance
    error amplifier, quickstart circuit for enhanced startup, trimmed
    internal bandgap reference, current sensing comparator, and a totem
    pole output ideally suited for driving a power MOSFET.
    Also included are protective features consisting of an overvoltage
    comparator to eliminate runaway output voltage due to load removal,
    input undervoltage lockout with hysteresis, cyclebycycle current
    limiting, multiplier output clamp that limits maximum peak switch
    current, an RS latch for single pulse metering, and a drive output high
    state clamp for MOSFET gate protection. These devices are
    available in dualinline and surface mount plastic packages.
