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 (ICE) 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 fMAX1 or
fMAX2 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.
fMAX1 is defined by fMAX1 = 0.05/tD(OFF)I. tD(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.
tD(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 TJMAX. tD(OFF)I is
important when controlling output ripple under a lightly loaded
condition.
fMAX2 is defined by fMAX2 = (PD - PC)/WOFF. The allowable
dissipation (PD) is defined by PD = (TJMAX - TC)/RθJC. The sum
of device switching and conduction losses must not exceed PD.
A 50% duty factor was used (Figure 10) and the conduction
losses (PC) are approximated by PC = (VCE • ICE)/2. WOFF is
defined as the integral 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 (ICE = 0A).
The switching power loss (Figure 10) is defined as fMAX2 •
WOFF. Turn-on switching losses are not included because they
can be greatly influenced by external circuit conditions and com-
ponents.
