Notes:
1/ Recovery time is measured from the initiation of the transient to where V
OUT
has returned to within ±1% of V
OUT
at 50% load.
2/ 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 8) while
power is applied to the input.
3/ 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.
4/ Above +125
°
C case, derate output power linearly to 0 at +135
°
C case.
5/ Input step transition time between 2 and 10 microseconds.
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 will interfere with the operation of the load fault detection circuitry, appearing as a short circuit during turn on.
7/ Load step transition time between 2 and 10 microseconds.
8/ Bandwidth guaranteed by design. Tested for 20 KHz.
9/ Load current split equally between +V
OUT
and -V
OUT.
10/ When operating with unbalanced loads, at least 25% of the load must be on the positive output to maintain regulation.
11/ Parameter guaranteed by line and load regulation tests.
12/ 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 II.
13/ Up to 90% of full power is available from either output provided the total output does not exceed 30 watts.
