Regulators
The MC34063A Series is a monolithic control circuit containing the
primary functions required for DCtoDC 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 StepDown and StepUp and
VoltageInverting applications with a minimum number of external
components. Refer to Application Notes AN920A/D and AN954/D
for additional design information.
