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) so that
the conduction losses (PC) can be approximated by PC =
(VCE x ICE)/2. WOFF is defined as the sum of the instanta-
neous 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 fMAX1 x
WOFF. Turn on switching losses are not included because
they can be greatly influenced by external circuit conditions
and components.
