    Buck Regulator General Description Features The Micrel MIC4782 is a high efficiency dual PWM buck
    (step-down) regulator that provides dual 2A output current.
    The MIC4782 operates at 1.8MHz. A proprietary internal
    compensation technique allows a closed loop bandwidth of
    over 200kHz. The low on-resistance internal P-Channel MOSFET of the
    MIC4782 allows efficiencies over 92%, reduces external
    components count and eliminates the need for an
    expensive current sense resistor.
    The MIC4782 operates from 3.0V to 6.0V input and the
    output can be adjusted down to 0.6V. The device can
    operate with a maximum duty cycle of 100% for use in lowdropout conditions. The MIC4782 is available in the exposed pad 16-pin
    3mm x 3mm MLFВ® with a junction operating range from
    –20°C to +125°C.
