Notes: Electrical Performance Characteristics
1. Parameter is tested as part of design characterization or after design changes. Thereafter, parameter shall be guaranteed to
the limits specified.
2. Parameter verified during 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 200 mA or 20 percent of
the total output power, whichever is greater, be taken from the main (+5 volt) output.
4. Although operation with no load is permissible, heavy loading on the main (+5 volt) output may cause the output voltage of the
auxiliary outputs(±12 volt or ±15 volt) to rise out of regulation. It is therefore recommended that at least 50 mA or 20 percent of
the total output power, whichever is greater, be taken from the auxiliary (±12 volt or ±15 volt) outputs.
5. Unless otherwise specified, “Rated” load is 20W on the main (+5 volt) output and 10 watts each on the auxiliary (±12 volt or
±15 volt) outputs. Load currents of up to 5A and ±1A on the main and auxiliary outputs respectively are acceptable as long as
the total output power does not to exceed 40 watts.
6. Guaranteed for a D.C. to 20MHz bandwidth. Tested using a 20KHz to 10MHz bandwidth.
7. Capacitive load may be any value from 0 to the maximum limit without compromising dc performance.
8. A capacitive load in excess of the maximum limit may interfere with the proper operation of the converter’s overload protection,
causing erratic behavior during turn-on.
9. Overload power dissipation is defined as the device power dissipation with the load set such that V_OUT = 90% of nominal.
10. Load step transition time ³ 10 µs.
11. Recovery time is measured from the initiation of the transient to where V_OUT has returned to within ±1% of its steady state value.
12. Line step transition time ³ 100 µs.
13. Turn-on delay time from either a step application of input power or a logic low to a logic high transition on the inhibit pin(pin3 to
the point where V_OUT = 90% of nominal.
14. Load is varied for output under test while the remaining outputs are loaded at 50% of rated. Regulation relative to output voltage
at 50% rated load.
15. Although operation at temperatures between +85°C and +125°C is guaranteed, no parametric limits are
specified.
