AX3113A consists of step-down switching regulator with PWM control. These devise
    include a reference voltage source, oscillation circuit, error amplifier, internal PMOS and
    AX3113A provides low-ripple power, high efficiency, and excellent transient
    characteristics. The PWM control circuit is able to the duty ratio linearly form 0 up to 100%.
    An enable function, an over current protect function and short circuit protect function are
    built inside, and when OCP or SCP happens, the operation frequency will be reduced. Also,
    an internal compensation block is built in to minimum external component count.
    With the addition of an internal P-channel Power MOS, a coil, capacitors, and a diode
    connected externally, these ICs can function as step-down switching regulators. They serve
    as ideal power supply units for portable devices when coupled with the SOP-8L package,
    providing such outstanding features as low current consumption. Since this converter can
    accommodate an input voltage up to 23V, it is also suitable for the operation via an AC
