5. Low duty cycle pulse techniques are used during test to maintain junction temperature as close to ambient temperature as poss ible.
6. If the output switch is driven into hard saturation (non?Darlington configuration) at low switch currents (≤ 300 mA) and high driver currents
(≥ 30 mA), it may take up to 2.0 s for it to come out of saturation. This condition will shorten the off time at frequencies ≥ 30 kHz, and is
magnified at high temperatures. This condition does not occur with a Darlington configuration, since the output switch cannot saturate. If a
non?Darlington configuration is used, the following output drive condition is recommended:

* The 100 resistor in the emitter of the driver device requires about 7.0 mA before the output switch conducts.

Features
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.
