The NCP3063 Series is a higher frequency upgrade to the popular
MC34063A and MC33063A monolithic DCDC converters. These
devices consist of an internal temperature compensated reference,
comparator, a controlled duty cycle oscillator with an active current
limit circuit, a driver and a high current output switch. This series was
specifically designed to be incorporated in StepDown, StepUp and
VoltageInverting applications with a minimum number of external
components.
