    MIC2253
    3.5A 1MHz High Efficiency
    Boost Regulator with OVP and Softstart General Description Features The MIC2253 is a high power density 1MHz PWM DC/DC
    boost regulator. The 3.5A minimum switch current limit
    combined with a 1MHz switching frequency allows the
    MIC2253 to use smaller inductors and deliver high power
    in a tiny solution size.
    The 2.5V to 10V input voltage range of MIC2253 allows
    direct operation from 1 and 2 cell Li-ion as well as 3 to 4
    cell NiCad, NiMH, Alkaline or lithium batteries. Maximum
    battery life is assured with a low 0.1µA shutdown current.
    The MIC2253 is available in a low profile 12-pin 3mm x
    3mm MLF© package. To prevent a high inrush current, a
    minimum 1ms soft-start period is set by default and the
    MIC2253 has the ability to extend the soft-start period with
    an external capacitor.
