The “total” specification is the maximum combined current/power of both outputs. 4. effect on negative VOuT referenced to 50%/50% loads. 50% to 10% with the opposite output held at 50% (applied to both outputs), see Figure 20 on page 16. Simultaneously 30%-70% 70%-30%. 5. indefinite short circuit protection not guaranteed above 125°C (case). 6. recovery time is measured from application of the transient to point at which VOuT is within regulation. 7. Step transition time >10 µs. 8. Step transition time 100 µs ±20% 9. Measured on release from inhibit. 10. applies to each output. 11. no effect on dc performance. www.craneae.com/interpoint Page 12 of 23 Crane Aerospace & Electronics Power Solutions mHF+ Single, Dual and Triple DC-DC Converters 28 VOlT INPuT – 15 WaTT MHF+ rev aB - 2014.10.02 |
