Notes to SPECIFICATIONS
1. Operation outside absolute maximum/minimum limits may cause permanent damage to the device. Extended operation at the limits may permanently
degrade performance and affect reliability.
2. Device performance specified in Electrical Performance table is guaranteed when operated within recommended limits. Operation outside
recommended limits is not specified.
3. Parameter measured from 28V to 19 V or to 50V while loads remain fixed.
4. Parameter measured from nominal to minimum or maximum load conditions while line remains fixed.
5. Up to 750 mA is available from the dual outputs provided the total output power does not exceed 30W.
6. Guaranteed for a bandwidth of DC to 20MHz. Tested using a 20KHz to 2MHz bandwidth.
7. Load current is stepped for output under test while other outputs are fixed at half rated load.
8. Load current is fixed for output under test while other output loads are varied for any combination of minimum to maximum.
9. A capacitive load of any value from 0 to the specified maximum is permitted without comprise to DC performance. A capacitive load in excess of the
maximum limit may interfere with the proper operation of the converter’s short circuit protection, causing erratic behavior during turn on.
10. Parameter is tested as part of design characterization or after design or process changes. Thereafter, parameters shall be guaranteed to the limits
specified in the table.
11. Load transient rate of change, di/dt ≤ 2 A/µSec.
12. Recovery time is measured from the initiation of the transient to where VOUT has returned to within ±1% of its steady state value.
13. Line transient rate of change, dv/dt ≤ 50 V/µSec.
14. Turn on delay time is for either a step application of input power or a logical low to high transition on the enable pin (pin 3) while power is present at the
input.
