33063AP
DC-to-DC Converter
Control Circuits
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
www.DataSheet4SUt.ecpomDown 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.

Thigh = +70°C for MC34063A, + 85°C for MC33063A, +125°C for MC33063AV
4. Low duty cycle pulse techniques are used during test to maintain junction temperature as close to ambient temperature as possible.
5. 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 µs 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:
wIC output
Forced b of output switch : IC driver – 7.0 mA *
10
*The 100 resistor in the emitter of the driver device requires about 7.0 mA before the output switch conducts.
