CVA2417TX
APPLICATION INFORMATION
The CVA2417TX is a high voltage triple CRT driver suitable
for VGA, Super VGA, IBM
768 non-interlaced display applications.
features 80V operation and low power dissipation. The part is
housed in the industry standard 11 lead TO-220 molded
power package.
grounded for ease of manufacturing and RFI shielding.
Thermal Considerations
The transfer characteristics of the amplifier are shown in
Figure 2. Since this is a class A input stage, power supply
current increases as the input signal increases and
consequently power dissipation also increases.
dissipation per stage is 2.8W, increasing to 4.8W at minimum
output voltage.
The CVA2417TX cannot be used without heat sinking. Figure
2 shows the power dissipated in each channel over the
operating voltage range of the device, Typical "average"
power dissipation with the device output voltage at one half
the supply voltage is 2.8W per channel for a total dissipation
of 8.4W package dissipation. Under white screen conditions,
i.e.: 15V output, dissipation increases to 4.8W per channel or
14.4W total.
