    500kHz 4mm Г— 4mm Synchronous Buck Controller General Description Features The MIC2198 is a high-power 500kHz synchronous buck
    DC-to-DC controller housed in a small 4mm Г— 4mm MLFв„ў
    12-pin package. The MIC2198 operates from a wide 4.5V
    to 32V input and can be programmed for output voltages
    from 0.8V to 6V. The wide input voltage capability makes
    the MIC2198 an ideal solution for point-of-load DC-to-DC
    conversion in 5V, 12V and higher systems.
    The 500kHz switching frequency allows the use of a small
    inductor and small output capacitors. The current mode PWM
    control along with the external COMP pin allows for ease of
    stability compensation and fast transient response across a
    wide range of applications.
    An all N-Channel synchronous architecture and powerful
    output drivers allow up to 20A of output current capability.
    For higher efficiency at higher input voltages, refer to the
    300kHz MIC2199.
    The MIC2198 is available in a 12-pin 4mm Г— 4mm MLFв„ў
    package with a junction temperature range from –40°C to
    125В°C. 4.5V to 32V input range
