Notes
1. Up to 4 watts (80% of full power) is available from either output providing the
opposite output is carrying 20% of total power.
2. Shows regulation effect on the minus output during the defined cross loading
conditions, with 80% and 20% referring to the total output power of the
converter. See Figures 15 and 16.
3. Indefinite short circuit protection not guaranteed above 125°C (case).
4. Recovery time is measured from application of the transient to point at which
V
OUT
is within 1% of V
OUT
at final value.
5. Guaranteed but not tested.
