External Current Boost Connections for Ic Peak Greater than 1.5A
External NPN Switch
External NPN Saturated Switch (NOTE)
NOTE
If the 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 us 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.
