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 20 KHz to 2 MHz. 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.
