Notes
1.Applies to both outputs.
2.Maximum combined output power is 12 watts. A maximum of 90% is
available from either output.
3.20% to 80% load on the positive output and 80% to 20% on the
negative output. See Figure 8.
4.50% load on the positive output and 50% to 20% load on the nega-
tive output. 50% load on the negative output and
50% to 20% load on the positive output. See Figure 7.
5.Indefinite short circuit protection not guaranteed above 85°C case
temperature.
