    2mm × 2mm PWM Boost Regulator
    with Internal Schotty Diode General Description Features The MIC2290 is a 1.2MHz, PWM, boost-switching
    regulator housed in the small size 2mm × 2mm 8-pin MLF®
    package. The MIC2290 features an internal Schottky diode
    that reduces circuit board area and total solution cost. High
    power density is achieved with the MIC2290’s internal
    34V/0.5A switch, allowing it to power large loads in a tiny
    The MIC2290 implements a constant frequency 1.2MHz
    PWM control scheme. The high frequency operation saves
    board space by reducing external component sizes. The
    fixed frequency PWM topology also reduces switching
    noise and ripple to the input power source.
    The MIC2290’s wide 2.5V to 10V input voltage allows
    direct operation from 3-to 4-cell NiCad/NiMH/Alkaline
    batteries, 1-and 2-cell Li-Ion batteries, as well as fixed
    3.3V and 5V systems.
    The MIC2290 is available in a low-profile 2mm×2mm 8-pin
    MLF® leadless package and operates from a junction
    temperature range of –40°C to +125°C.
