(a) External NPN Switch
(b) External NPN Saturated Switch (See Note)

C
Peak Greater than 1.5A
Note: If the output switch is driven into hard saturation (non-Darlington configuration) at low switch currents ( 300mA) and
high driver currents ( 30mA), it may take up to 2.0
μ
s to come out of saturation. This condition will shorten the off time at
frequencies 30kHz, and is magnified at high temperature. 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.
