Notes to Specifications
1. Applicable to positive and negative outputs..
2. Maximum combined output is 12 watts. 10.8 watts (max.) is available from either output (90%).
3. Load current split equally between +V_OUT and –V_OUT.
4. 1.2 watt load on output under test, 1.2 watt to 10.8 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 2.0µs and 10µs.
8. Recovery time is measured from initiation of the transient to where V_OUT has returned to within ±1% of V_OUT at 50% load.
9. Input step transient time between 1.0µs and 10µs.
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.
