Notes
1. Maximum combined output power is 15 watts for both dual and triple models.
Dual output models: The maximum specification is the total output current/power.
Up to 80% of that total is available from either output provided the positive output maintains a minimum of 20% of the total power used.
Triple output models: The maximum combined power of the auxiliaries is 6 watts, of which 100% is available from either output.
2. Load regulation is not guaranteed below minimum load.
3. Converter should not be inhibited or operated below 12 Vin above 10
4
rads (Si) total dose.
4. Indefinite short circuit protection is not guaranteed above 85°C case.
