(See Note 5 )
Note 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 us 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.
