    MIC2288 Micrel, Inc. MIC2288
    1A 1.2MHz PWM Boost Converter in
    ×2 MLF™
    Thin SOT-23 and 2× General Description Features The MIC2288 is a 1.2MHz PWM, DC/DC boost switching
    regulator available in low-profile Thin SOT-23 and
    2mm × 2mm MLF™ package options. High power density is
    achieved with the MIC2288’s internal 34V/1A switch, allowing it to power large loads in a tiny footprint.
    The MIC2288 implements a constant frequency, 1.2MHz
    PWM, current mode control scheme with internal compensation that offers excellent transient response and output regulation performance. The high frequency operation saves
    board space by allowing small, low-profile, external components. The fixed frequency PWM topology also reduces
    spurious switching noise and ripple to the input power source.
    The MIC2288 is available in a low-profile Thin SOT-23-5
    package and a 2mm × 2mm MLF™-8 leadless package. The
    2mm × 2mm MLF™-8 package option has an output overvoltage protection feature.
    The MIC2288 has a junction temperature range of –40°C to
