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. www.onsemi.com 3 MC34063A, MC33063A, SC34063A, SC33063A, NCV33063A 18 OFF TIME (ms) 14 140 12 120 ON TIME (ms) 10 100 8 80 6 OFF TIME (ms) 4 60 40 FREQUENCY (kHz) 2 0 0.0 0.5 1.0 1.5 2.0 2.5 3.0 3.5 4.0 4.5 20 200 mV/DIV 160 V OSC , OSCILLATOR VOLTAGE (V) 16 ON TIME (ms), FREQUENCY (kHz) 180 VCC = 5.0 V, Pin 7 = VCC Pin 5 = GND, TA = 25C VCC = 5.0 V Pin 7 = VCC Pin 2 = GND Pins 1, 5, 8 = Open CT = 1.0 nF TA = 25C 0 5.0 10 ms/DIV Figure 4.
