    3 Applications General Description The TC115 is a high-efficiency step-up DC/DC
    converter for small, low input voltage or batterypowered systems. This device has a start-up voltage
    of 0.9V and a typical supply current of 80 ВµA. Phase
    compensation and soft-start circuitry are included onchip. Unlike conventional PWM step-up converters,
    the TC115 automatically shifts to pulse frequency
    modulation (PFM) at low loads, resulting in reduced
    supply current and improved efficiency. Pagers

    Local +3V to +5V Supplies The TC115 requires only an external diode, an inductor
    and a capacitor, while supporting typical output currents of 140 mA. Supply current is reduced to less than
    0.5 ВµA (max) when SHDN input is brought low.
    Small size, low installed cost and low supply current
    make the TC115 step-up converter ideal for use in a ...
