ATW28XXD Series
Notes to Specifications
1 Parameter guaranteed by line, load and cross regulation tests.
2 Up to 90% of full power is available from either output provided the total output does not exceed 30W.
3 Bandwidth guaranteed by design. Tested for 20KHz to 2MHz.
4 Load current split equally between +V
and –V
.
5 Three-watt load on output under test, 3 watt to 27 watt load change on other output.
6 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.
7 Parameter shall be tested as part of design characterization and after design or process changes.
Thereafter, parameters shall be guaranteed to the limits specified in Table I.
8 An overload is that condition with a load in excess of the rated load but less than that necessary to
trigger the short circuit protection and is the condition of maximum power dissipation.
9 Load step transition time between 2 and 10 microseconds.
10 Recovery time is measured from the initiation of the transient to where V
OUT
has returned to within ±1
percent of V
at 50 percent load.
11 Input step transition time between 2 and 10 microseconds.
12 Turn-on delay time measurement is for either a step application of power at the input or the removal of
ground signal from the inhibit pin (pin 8) while power is applied to the input.
