(See Note 5)

NOTE:

5. 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 2.0µs for it to come out of saturation. This condition will shorten the off time at frequencies≥30kHz, 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:
