SWITCHING TIME NOTES
In resistive switching circuits, rise, fall, and storage times have been defined and apply to both current and
voltage
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.
tsv = Voltage Storage Time, 90% IB1 to 10% VCEM
trv = Voltage Rise Time, 10–90% VCEM
tfi = Current Fall Time, 90–10% ICM
tti = Current Tail, 10–2% ICM
tc = Crossover Time, 10% VCEM to 10% ICM
An enlarged portion of the turn–off waveforms is shown in Figure 13 to aid in the visual identity of these terms.
For the designer, there is minimal switching loss during storage time and the predominant switching power losses
occur during the crossover interval and can be obtained using the standard equation from AN–222:
PSWT = 1/2 VCCIC(tc) f
Typical inductive switching waveforms are shown in Figure 14. In general, trv + tfi ≈ tc. However, at lower test
currents this relationship may not be valid.
As is common with most switching transistors, resistive switching is specified at 25
and has become a
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 (tc and tsv) which are
guaranteed at 100 .
