4 / 7 page 4 www.irf.com AMA28XXS Series Dynamic Characteristics -55°C ≤ TCASE ≤ +125°C, VIN=28 VDC ±5%, C L=0, unless otherwise specified. 1. Parameter guaranteed by line and load regulation tests. 2. Bandwidth guaranteed by design. Tested for 20KHz to 2.0MHz. 3. 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 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. 4. Parameter shall be tested as part of design characterization and after design or process changes. Parameters shall be guaranteed to the limit specified in Electrical Specifications. 5. Load step transition time between 2 and 10 microseconds. 6. Recovery time is measured from the initiation of the transient to where V OUT has returned to within ±1 % of VOUT at 50 percent load. 7. Input step transition time between 2 and 10 microseconds. 8. 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.
