MC34063A, MC33063A, SC34063A, SC33063A, NCV33063A 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.

Low duty cycle pulse techniques are used during test to maintain junction temperature as close to ambient temperature as possible. 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 ms 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: IC output w 10 Forced b of output switch : IC driver - 7.0 mA * * The 100 W resistor in the emitter of the driver device requires about 7.0 mA before the output switch conducts.

Vsat = Saturation voltage of the output switch. VF = Forward voltage drop of the output rectifier. The following power supply characteristics must be chosen: Vin - Nominal input voltage. Vout - Desired output voltage, |V out| + 1.25 1 ) R2 R1 Iout - Desired output current. fmin - Minimum desired output switching frequency at the selected values of Vin and IO. Vripple(pp) - Desired peak-to-peak output ripple voltage. In practice, the calculated capacitor value will need to be increased due to its equivalent series resistance and board layout. The ripple voltage should be kept to a low value since it will directly affect the line and load regulation. NOTE: For further information refer to Application Note AN920A/D and AN954/D.
