10.10 Conclusion

Video response is always a compromise between several parameters. For example, the rise/fall time

improvement leads to the overshoot deterioration.

The recommended way to optimize the video response is:

1

To set R10+R11 for arcing protection (min. 300

Ω)

2. To adjust R20 and R10+R11.

Increasing their value increases the

3. To adjust L1

Increasing L1 speeds up the device but increases the overshoot.

4. To adjust the input network for the final dynamic tunning (e.g.: critical damping)

We recommend our customers to use the schematic shown on Figure 23 as a starting point for the video

board and then to apply the optimization they need.
