Radiation Performance Characteristics

Notes for the 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.

These are beginning-of-life (BOL) limits. End-of-life (EOL) limits are -3% and +3% of nominal limit for Min and

Max, respectively.

4.

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

5.

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.

6.

nominal.

7.

Load step slew rate

≤ 0.5A/µs.

8.

steady state value.

9.

Line step slew rate

≤1.0V/µs.

10. Turn-on delay time from either a step application of input power or a logic low to a logic high transition on the

11. MIL-HDBK MOSFET failure rates replaced by empirical failure rate data supplied by International Rectifier.
