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 output may cause the output
voltage of the auxiliary outputs to drop out of regulation. It is therefore recommended that at least 200mA
or 20 percent of the total output power, whichever is greater, be taken from the main output.
4. Although operation with no load is permissible, heavy loading on the main output may cause the output
voltage of the auxiliary outputs to rise out of regulation. It is therefore recommended that at least 50mA
or 20 percent of the total output power, whichever is greater, be taken from the auxiliary (±12 volts)
output.
5. Unless otherwise specified, “Rated” load is 13.2W on the main output and 10W each on the auxiliary
outputs.
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. 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.
8. Overload power dissipation is defined as the device power dissipation with the load set such that V_OUT =
90% of nominal.
9. Load step transition time ≥ 10µs.
10. Recovery time is measured from the initiation of the transient to where V_OUT has returned to within ±1% of
its steady state value.
11. Line step transition time ≥ 100µs.
12. 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 (pin 3) to the point where V_OUT = 90% of nominal.
13. 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.
14. Although operation at temperatures between +85°C and +125°C, is guaranteed, no parametric limits are
specified.
