3 / 12 page  47 SMSA SERIES 5 WATT DC/DC CONVERTERS ® Electrical Characteristics: 25°C Tc, 28 VDC Vin, 100% load, radiation level O, unless otherwise specified. 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 VOUT is within 1% of VOUT at final value. 5. Guaranteed but not tested.
