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