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 DC to 20 MHz bandwidth. Tested using a 20 kHz to 10 MHz bandwidth.

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.

9. Load step transition time

10 s.

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 3) to the point

13. Total regulation at EOL is +/- 3% maximum.

14. The input current is minimized with an output load of 300mW to 400mW. If a system design requires converter operation at or near zero

load (e.g. a system standby mode), then it is recommended that a resistive preload of 300mW to 400mW will be added to converter’s

output (s). The small preload will reduce the converter’s “no load” input current from approximately 70mA to approximately 30mA.
