    DESCRIPTION
    The MP2105 is a 1MHz constant frequency,
    current mode, PWM step-down converter. The
    device integrates a main switch and a
    synchronous rectifier for high efficiency without
    an external Schottky diode. It is ideal for
    powering portable equipment that runs from a
    single cell Lithium-Ion (Li+) battery. The
    MP2105 can supply 800mA of load current from
    a 2.5V to 6V input voltage. The output voltage
    can be regulated as low as 0.6V. The MP2105
    can also run at 100% duty cycle for low dropout
    applications.
    The MP2105 is available in a low profile (1mm)
    5-pin, TSOT package.
