1.
Parameter is tested as part of design characterization or after design changes. Thereafter, parameter shall be
guaranteed to the limits specified.
2.
Parameter verified during line and load regulation tests.
3.
Although operation with no load is permissible, light loading on the main (+5 volt) output may cause the output voltage
of the auxiliary outputs(±12 volt or ±15 volt) to drop out of regulation. It is therefore recommended that at least 200 mA
or 20 percent of the total output power, whichever is greater, be taken from the main (+5 volt) output.
4.
Although operation with no load is permissible, heavy loading on the main (+5 volt) output may cause the output
voltage of the auxiliary outputs(±12 volt or ±15 volt) to rise out of regulation. It is therefore recommended that at least
50 mA or 20 percent of the total output power, whichever is greater, be taken from the auxiliary (±12 volt or ±15 volt)
outputs.
5.
Unless otherwise specified, “Rated” load is 20W on the main (+5 volt) output and 10 watts each on the auxiliary (±12
volt or ±15 volt) outputs. Load currents of up to 5A and ±1A on the main and auxiliary outputs respectively are
acceptable as long as the total output power does not to exceed 40 watts.
6.
Guaranteed for a D.C. to 20MHz bandwidth. Tested using a 20KHz to 10MHz bandwidth.
7.
Capacitive load may be any value from 0 to the maximum limit without compromising dc performance.
8.
A capacitive load in excess of the maximum limit may interfere with the proper operation of the converter’s overload
protection, causing erratic behavior during turn-on.
9.
Overload power dissipation is defined as the device power dissipation with the load set such that V
OUT = 90% of
nominal.
10.
Load step transition time
≤10 mSec.
11.
Recovery time is measured from the initiation of the transient to where V
OUT has returned to within ±1% of
its steady
state value.
12.
Line step transition time
≤100 mSec.
13.
Turn-on delay time from either a step application of input power or a logic low to a logic high transition on the inhibit pin
(pin 3) to the point where V
OUT = 90% of nominal.
14.
Load is varied for output under test while the remaining outputs are loaded at 50% of rated. Regulation relative to
output voltage at 50% rated load.
