    Mobile VID, 600kHz,
    Synchronous Buck Controller U FEATURES DESCRIPTIO ■ The LTC®3730 is a PolyPhase® synchronous step-down
    switching regulator controller that drives all N-channel
    external power MOSFET stages in a phase-lockable fixed
    frequency architecture. The 3-phase controller drives its
    output stages with 120° phase separation at frequencies of
    up to 600kHz per phase to minimize the RMS losses in both
    the input and output filter capacitors. The 3-phase technique effectively triples the fundamental frequency, improving transient response while operating each controller
    at an optimal frequency for efficiency and ease of thermal
    design. Light load efficiency is optimized by using a choice
    of output Stage Shedding or Burst Mode technology.
    An internal operational amplifier provides mode selectable
    output voltage programming in conjunction with the internal VID voltage control DAC. ■
