Shows regulation effect on the minus output during the defined cross loading conditions: +PO = 30-70%, -PO = 70-30% and -PO = 30-70%, +PO = 70-30. See Figure 24, Figure 25 and Figure 26 on page 12. 4. The inhibited input current is tested with <0.8 volts on the inhibit. 5. For RHA L, 50 krad converters, the pre-radiation spec for Iin Inhibit is 7 mA max. 6. Tested with a 2 µH external input inductor. 7. Indefinite short circuit protection not guaranteed above 125°C (case). 8. Recovery time is measured from application of the transient to point at which VOuT is within 1% of VOuT at final value. 9. Applies to each output. Crane Aerospace & Electronics Power Solutions SMSA Single and Dual DC-DC Converters Page 9 of 15 28 Volt input – 5 Watt www.craneae.com/interpoint SMSA Rev AE - 2016.02.01 |
