    300kHz 4mm Г— 4mm Synchronous Buck Converter General Description Features The MIC2199 is a high-power 300kHz synchronous buck
    DC-to-DC controller housed in a small 4mm × 4mm MLF™
    12-pin package. The MIC2199 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 MIC2199 an ideal solution for point-of-load DC-to-DC
    conversion in 5V, 12V, 24V, and 28V systems.
    The 300kHz 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.

    The MIC2199 is available in a 12-pin 4mm × 4mm MLF™
    package with a junction temperature range from –40°C to
    125В°C. 4.5V to 32V input range
