AMA28XXD Series

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%).

3.

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.

8.

±1% of

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.
