POWER DISSIPATION

The total power dissipation is the sum of the static DC and the dynamic dissipation:

The static DC power dissipation is approximately:

The dynamic dissipation is, in the worst case (1 pixel On/ 1 pixel Off pattern):

where f is the video frequency and K the ratio between the active line and the total horizontal line duration.

Example:

We have:

Therefore:

Note 6: This worst thermal case must only be considered for TJmax calculation. Nevertheless, during the average life

of the circuit, the conditions are closer to the white picture conditions.
