AHF28XX Series
1. Parameter guaranteed by line load and cross regulation tests.
2. Up to 90 percent of full power is available from either output provided the total output does not exceed 12W.
3. Bandwidth guaranteed by design. Tested for 20 kHz to 2 MHz.
4. Load current split equally between +V
and –V
.
5. 1.2 watt load on output under test, 1.2 watt to 10.8 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 VI.
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
a ground signal from the inhibit pin (pin 1) while power is applied to the input.
