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.
For ARH2803.3, maximum output power is 25 W and maximum current is 7575 mA at TC = +125C (Subgroup 2)
4.
Output is measured for all combinations of line and load. Only the minimum and maximum readings for the output are recorded.
5.
Load step transition time
≥ 10S.
6.
Recovery time is measured from the initiation of the transient to where VOUT 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 +25C, subgroups 2 and 5 at +125C and subgroups 3 and 6 at -55C.
