ART28XXT Series
Group A Tests V
IN= 28Volts, CL =0 unless otherwise specified.
Notes to Group A Test Table
1.
Parameter verified during dynamic load regulation tests.
2.
Guaranteed for DC to 20 MHz bandwidth. Test conducted using a 20KHz to 2MHz bandwidth.
3.
Load current is stepped for output under test while other outputs are fixed at half rated load.
4.
Each output is measured for all combinations of line and load. Only the minimum and maximum readings for each output are recorded.
5.
Load step transition time
≥ 10µS.
6.
Recovery time is measured from the initiation of the transient to where V
OUT has returned to within ±1% of its steady state value.
7.
Turn on delay time is tested by application of a logical low to high transition on the enable pin (pin 3) with power present at the input.
8.
Subgroups 1 and 4 are performed at +25ºC, subgroups 2 and 5 at -55ºC and subgroups 3 and 6 at +125ºC.
