Electrical Performance Characteristics ( continued )

Notes: Electrical Performance Characteristics

Parameter is tested as part of design characterization or after design changes. Thereafter, parameter shall

be guaranteed to the limits specified.

Parameter verified during line and load regulation tests.

Limit represents 80% of total rated output current. To achieve rated output power, the remaining 20% of

the total rated output current must be provided by the other output.

Load current split equally between outputs on dual output models.

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.

Guaranteed for a D.C. to 20MHz bandwidth. Tested using a 20KHz to 10MHz bandwidth.

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.

Overload power dissipation is defined as the device power dissipation with the load set such that VOUT =

90% of nominal.

Load step transition time

≥ 10 µs.

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 µs.

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 where VOUT = 90% of nominal.

13. Although operation at temperatures between +85°C and +125°C is guaranteed, no parametric limits are

specified.
