(2) In the non-Darlington configuration, if the output switch is driven into hard saturation at low switch currents ( ≤300 mA) and high driver currents ( ≥30 mA), it may take up to 2 μs for the switch to come out of saturation. This condition effectively shortens the off time at frequencies ≥30 kHz, becoming magnified as temperature increases. The following output drive condition is recommended in the non-Darlington configuration: Forced β of output switch = IC,SW / (IC,driver – 7 mA) ≥ 10, where ~7 mA is required by the 100-Ω resistor in the emitter of the driver to forward bias the Vbe of the switch.
