1.5 A, Step-Up/Down/Inverting Switching Regulators
The MC34063A Series is a monolithic control circuit containing the
primary functions required for DC−to−DC converters. These devices
consist of an internal temperature compensated reference,
comparator, controlled duty cycle oscillator with an active current
limit circuit, driver and high current output switch. This series
was specifically designed to be incorporated in Step−Down and
Step−Up and Voltage−Inverting applications with a minimum number of
external components. Refer to Application Notes AN920A/D and
AN954/D for additional design information.
