Notes to Specifications

1. Applicable to positive and negative outputs..

2. Maximum combined output is 5.0 watts. 4.0 watts (max.) is available from either output (80%).

4. 1.0 watt load on output under test, 1.0 watt to 4.0 watt load change on other output.

5. Capacitive value may be any value from 0 to the maximum limit without compromising DC performance. A capacitive load in

excess of the maximum limit will not disturb loop stability but may interfere with the operation of the load fault detection circuitry,

appearing as a short circuit during turn-on.

6. Parameter shall be tested as part of design characterization and after design or process changes. Thereafter, parameters shall be

guaranteed to the limit specified.

7. Load step transition time between 2 and 10 microseconds.

9. Input step transient time between 1 and 10 microseconds.

10 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 while power is applied to the input.
