Power Dissipation
The dissipated power in R
3
and R
6
could calculated as
follows:
We assume that:
V
ON
= 40V
V
OFF
= -20V
H sync timing frequency = 60kHz
C
L
= 5nF
The value of V
L
, the left over voltage in the capacitors in that
case is 23V for the positive discharge and 3.3V for the
negative discharge.
The voltage change across the capacitor is therefore 23V,
see Figure 25.
The stored energy in the capacitor is:
The energy which is stored in the capacitor will be
dissipated on the resistor see Figure 26. The switch will
close 2 x 60,000 in every second.
Since the process will be repeated 2 times, for the CKV and
the CKVB. In 0,000 cycles per second the power dissipation
in R
3
and R
6
becomes:
For different values of V
ON
, V
OFF
, C
L
and H sync timing
frequency, the worst case dissipation can be calculated in a
similar matter. The value of the R
3
and R
6
must be selected
such that the capacitor C
L
is discharged via R
3
or R
6
resistor
in one half period of the H sync timing.
Figures 11 and 12 show the total power dissipation over a
range of possible voltages, operating frequencies and loads.
Care should be taken to prevent the power from exceeding
the maximum rating of the package, as shown in Figure 13.
