Electrical Characteristics Notes
1. Converter will undergo input over-voltage shutdown.
2. Derate output power to 50% of rated power at Tcase = 135 C.
3. High or low state of input voltage must persist for about 200s to be acted on by the lockout or shutdown circuitry.
4. Current limit inception is defined as the point where the output voltage has dropped to 90% of its nominal value.
5. Parameter not tested but guaranteed to the limit specified.
6. Load current transition time ≥ 10 s.
7. Settling time measured from start of transient to the point where the output voltage has returned to ±1% of its final value.
8. Line voltage transition time ≥ 250 s.
9. Input voltage rise time ≥ 250 s.
10. Operating the converter at a synchronization frequency above the free running frequency will slightly reduce the converter’s efficiency and may also cause a
slight reduction in the maximum output current/power available. For more information consult the factory.
11. After a disable or fault event, module is inhibited from restarting for 300 ms. See Shut Down section.
12. All +Vout and -Vout voltage measurements are made with Kelvin probes on the output leads.
13. SHARE pin outputs a power failure warning pulse during a fault condition. See Current Share section.
14. Only the ES and HB grade products are tested at three temperatures. The C grade products are tested at one temperature. Please refer to the ESS table for
details.
15. These derating curves apply for the ES- and HB- grade products. The C- grade product has a maximum case temperature of 100 C and a maximum junction
temperature rise of 20 C above TCASE.
16. Converter delivers current into a persisting short circuit for up to 1 second. See Current Limit in the Application Notes section.
