The MC33063ASeries 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.
