Operating
-55°C to 135°C case
Storage -65°C to +135°C
Notes:
1.
Tested at each output.
2.
Parameter guaranteed by line and load regulation tests.
3.
Although operation with no load is permissible, light loading on the main (+5 volt) output may cause the output voltage of the auxiliary outputs
(±12 volt or ±15 volt) to drop out of regulation. It is therefore recommended that at least 100 mA or 20 percent of the output power, whichever is
greater, be taken from the main (+5 volt) output.
4.
Total combined output power - 30 watts.
5.
Bandwidth guaranteed by design. Tested for 20 KHz to 2 MHz.
6.
An overload is that condition with a load in excess of the rated load but less than that necessary to trigger the overload protection circuit and is the
condition of maximum power dissipation.
7.
Load step transition time between 2 and 10 microseconds.
8.
Recovery time is measured from the initiation of the transient to where VOUT has returned to within ±1 percent of VOUT at 50 percent load.
9.
Input step transition time between 2 and 10 microseconds.
10. Parameter shall be tested as part of design characterization and after design or process changes. Thereafter parameters shall be guaranteed to the
limits specified in the table.
11. Turn on delay time measurement is for either a step application of power at the input or the removal of a ground signal from the inhibit pin (pin 8) while
power is applied to the input.
