    Package The MIC45116 is a synchronous step-down regulator
    module, featuring a unique adaptive ON-time control
    architecture. The module incorporates a DC/DC
    controller, power MOSFETs, bootstrap diode, bootstrap
    capacitor, and an inductor in a single package;
    simplifying the design and layout process for the end
    This highly integrated solution expedites system
    design and improves product time-to-market. The
    internal MOSFETs and inductor are optimized to
    achieve high efficiency at a low output voltage. The fully
    optimized design can deliver up to 6A current under a
    wide input voltage range of 4.75V to 20V without
    requiring additional cooling.
    The MIC45116-1 uses HyperLight LoadВ® (HLL) which
    maintains high efficiency under light load conditions by
    transitioning to variable frequency, discontinuousmode operation. The MIC45116-2 uses Hyper Speed ...
