Operating Frequency Information
Operating frequency information for a typical device (Figure
10) is presented as a guide for estimating device performance
for a specific application. Other typical frequency vs collector
current (I
CE
) plots are possible using the information shown
for a typical unit in Figures 7, 8 and 9. The operating
frequency plot (Figure 10) of a typical device shows f
MAX1
or
f
MAX2
whichever is smaller at each point. The information is
based on measurements of a typical device and is bounded
by the maximum rated junction temperature.
f
MAX1
is defined by f

. t
D(OFF)I
deadtime
(the denominator) has been arbitrarily held to 10% of the on-
state time for a 50% duty factor. Other definitions are
possible. t
D(OFF)I
is defined as the time between the 90%
point of the trailing edge of the input pulse and the point
where the collector current falls to 90% of its maximum
value. Device turn-off delay can establish an additional
frequency limiting condition for an application other than
T
JMAX
. t
D(OFF)I
is important when controlling output ripple
under a lightly loaded condition.
f

sipation (P

. The sum of
device switching and conduction losses must not exceed P
D
.
A 50% duty factor was used (Figure 10) so that the conduction
losses (P
C
) can be approximated by P
C
= (V
CE
x I
CE
)/2. W
OFF
is defined as the sum of the instantaneous power loss starting
at the trailing edge of the input pulse and ending at the point
where the collector current equals zero (I
CE
- 0A).
The switching power loss (Figure 10) is defined as f
MAX1
x
W
OFF
. Turn on switching losses are not included because
they can be greatly influenced by external circuit conditions
and components.
