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.

s.

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)

13. For operation at temperatures between +85°C and +125°C, de-rate the maximum output power linearly from 100% to 75%.
