This condition will shor ten 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 nonDarlington configuration is used, the following output drive condition is recommended: Forced Bata of output switch: Ic output / ( Ic driver – 7mA*) >= 10 * The 100ohm resis tor in the emitter of the driver divide requires about 7mA before the output switch conduc ts.
