Regulators
MC34063A and MC33063A monolithic DC−DC 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 Step−Down, Step−Up and
Voltage−Inverting applications with a minimum number of external
components.
