The AP8363 is a compact, high efficiency, and
low voltage step-up DC/DC converter including
an error amplifier, ramp generator, comparator,
switch pass element and driver in which providing
a stable and high efficient operation over a wide
range of load currents. It operates in stable
waveforms without external compensation.
The low start-up input voltage below 1.6V. The
high switching rate minimized the size of external
components. Besides, the 19μA low quiescent
current together with high efficiency maintains
long battery lifetime.
The output voltage is set with two external
resistors.
