4 / 7 page 4 www.irf.com AMA28XXD Series Dynamic Characteristics -55°C ≤ TCASE ≤ +125°C, VIN = 28VDC ±5%, C L = 0, unless otherwise specified. 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. Load current split equally between +VOUT and –VOUT. 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. Recovery time is measured from initiation of the transient to where VOUT has returned to within ±1% of VOUT at 50% load. 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.
