CORPORATION

APPLICATION INFORMATION

FIGURE 4. CVA2422TL DC Characteristics

The CVA2422TL is a high voltage triple CRT driver suitable for

VGA, Super VGA, IBM^®8514, 1280 x 1024 and 1024 x 768

non-interlaced display applications. The CVA2422TL features

80V operation. The part is housed in the industry standard 11

lead TO-220 molded power package. The heat sink is floating

and may be grounded for ease of manufacturing and RFI

shielding.

Thermal Considerations

VOLTAGE

POWER

The transfer characteristics of the amplifier are shown in

Figure 4. Since this is a class A input stage, power supply

current increases as the input signal increases and

consequently power dissipation also increases.

The CVA2422TL cannot be used without heat sinking. Figure

2 shows the power dissipated in each channel over the

operating voltage range of the device. Under white screen

conditions, i.e.: 20V output, dissipation increases to 16W

total. The CVA2422TL case temperature must be maintained

below +90^oC. If the maximum expected ambient temperature

is +50^oC, then a heat sink is needed with thermal resistance

equal to or less than:

INPUT VOLTAGE

1G-26

(90 − 50^oC)

R_th

= 2.5^oC/W

16W

The CVA2422TL maximum load is 600Ω to ground or V⁺.

The output of CVA2422TL is not short circuit proof. Any

resistance to V⁺or Ground should be > 600Ω.
