... BU808DFP Switching Time Inductive Load at 16KHZ BASE DRIVE INFORMATION In order to saturate the power switch and reduce conduction losses, adequate direct base current I has to be provided for the lowest gain 100 C (line scan phase). On the other hand, negative base current I must be provided to B2 turn off the power transistor (retrace phase) ...
