    MIC24420/MIC24421
    2.5A Dual Output PWM Synchronous
    Buck Regulator IC General Description Features The MIC24420/MIC24421 are synchronous PWM dual
    output step down converters with internal 2.5A high-side
    switches. The MIC24420/MIC24421 has an integrated lowside gate driver for synchronous step-down conversion by
    connecting an external N-channel MOSFET to achieve
    high efficiencies in low duty-cycle applications.
    The MIC24420 switching frequency is 1MHz and the
    MIC24421 switching frequency is 500kHz. A patented
    control scheme allows the use of a wide range of output
    capacitance from small ceramic capacitors to large
    electrolytic types with only one compensation component.
    A 2% output voltage tolerance over the temperature range
    allows the maximum level of system performance. The
    MIC24420/MIC24421 power good signal allows full control
    for sequencing the output voltages with minimum external
    components.
    An adjustable current limit allows the use of smaller
    inductors in lower current applications.
    The MIC24420/MIC24421 is available in a ePad 24-pin
    В®
    4mm x 4mm MLF package, and has an operating junction
    temperature range of –40°C to +125°C. 4.5V to 15V input voltage range ...
