Notes: Electrical Performance Characteristics Table
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. Output load current must be distributed such that at least 20% of the total load current is being provided by one of the outputs.
4. Load current split equally between outputs on dual output models.
5. Cross regulation is measured with 20% rated load on output under test while changing the load on the other output from 20% to
80% of rated.
6. Guaranteed for a D.C. to 20 MHz bandwidth. Tested using a 20 kHz to 10 MHz bandwidth using the circuit shown below.
7. 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 may interfere with the proper operation of the converter’s overload protection, causing erratic
behavior during turn-on.
8. Overload power dissipation is defined as the device power dissipation with the load set such that VOUT = 90% of nominal.
9. Load step transition time  10 s.
10. Recovery time is measured from the initiation of the transient to where VOUT has returned to within ±1% of its steady state value
11. Line step transition time 100 s.
12. 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 4)
to the point where VOUT = 90% of nominal.
13. For operation at temperatures between +85°C and +125°C, de-rate the maximum output power linearly from 100% to 75%.
