waveforms since they are in phase. However, for inductive loads, which are common to SWITCHMODE power
supplies and hammer drivers, current and voltage waveforms are not in phase. Therefore, separate measurements
must be made on each waveform to determine the total switching time. For this reason, the following new terms
have been defined.
occur during the crossover interval and can be obtained using the standard equation from AN–222:
benchmark for designers. However, for designers of high frequency converter circuits, the user oriented
specifications which make this a “SWITCHMODE” transistor are the inductive switching speeds (t
are guaranteed at 100°C.
RESISTIVE SWITCHING PERFORMANCE
In resistive switching circuits, rise, fall, and storage times have been defined and apply to both current and voltage
For the designer, there is minimal switching loss during storage time and the predominant switching power losses
In general, t
As is common with most switching transistors, resistive switching is specified at 25°C and has become a
