    MIC2250
    High-Efficiency Low EMI
    Boost Regulator General Description Features The MIC2250 is a general purpose DC/DC boost switching Over 80% efficient for a 300:1 load range
    regulator that features low noise, EMI reduction circuitry, 2.5V to 5.5V input voltage range
    and high efficiency across a wide output current range. Output voltage adjustable to 32V
    The MIC2250 is optimized for noise-sensitive hand held 52µA (typ) quiescent current
    battery powered applications. A proprietary control method Constant peak current control reduces output ripple
    allows low ripple across the output voltage and current
    ranges. The MIC2250 incorporates a pseudo-random EMI reduction circuitry
    dithering function to reduce EMI levels up to 10dB enabled Stable with small ceramic capacitors
    by the DITH pin. <1µA shutdown current
    The MIC2250 is designed for use with inductor values from UVLO and thermal shutdown
    4.7µH to 22µH, and is stable with ceramic capacitors from
    1µF to 22µF. 8-pin 2mm x 2mm leadless MLF® package (MIC2250)
    The MIC2250 attains a high peak efficiency up to 90% at 5-pin Thin SOT-23 package (MIC2250-1 & -2)
    100mA and excellent light load efficiency of 80% at 1mA. –40°C to +125°C junction temperature range
    High power density is achieved with the MIC2250’s
    internal 34V/2A rated switch, allowing it to power large
    loads in a tiny footprint.
    Applications
    The MIC2250-1 is available in a 5-pin Thin SOT-23 LCD/OLED display bias supply
    package with dithering disabled. While the MIC2250-2 is CCD bias supply
    available in a 5-pin Thin SOT-23 package with dithering Mobile Phones, PDA, Media Players, GPS PND ...
