    500kHz 1A SuperSwitcher™ Buck Regulator General Description Features The MIC4690 SuperSwitcher™ is an easy-to-use, 500kHz
    step-down PWM voltage regulator. The MIC4690 achieves
    over 1A of continuous output current over a wide input voltage
    range in an 8-lead SO (small outline) package.
    The high switching frequency of the MIC4690 allows the
    smallest surface-mount inductors and capacitors to be used.
    Internal compensation ensures fast transient response and a
    minimum amount of external components.
    The MIC4690 features a power SO-8 package with a special
    lead frame that allows over 1A of continuous current. The
    MIC4690, housed in an SO-8, can replace larger TO-220 and
    TO-263 packages in many applications.
    The MIC4690 allows for a high degree of safety. It has a wide
    input voltage range of 4V to 34V, allowing for it to be used in
    applications where input voltage transients may be present.
    Built-in safety features include over-current protection, frequency foldback protection, and thermal shutdown.
    The MIC4690 is available in an 8-lead SO package with a
    junction temperature range of –40°C to +125°C. SO-8 package with over 1A output current
    Fixed 500kHz operation
    Wide 4V to 34Vinput voltage range
    Output voltage adjustable to 1.23V
