Notes: Specification and Electrical Performance Characteristics

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.

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

4.

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.

5.

Overload power dissipation is defined as the device power dissipation with the load set such that both outputs are in a

short circuit mode.

6.

Load step transition time

≤ 10 µsec.

7.

state value.

8.

Line step transition time

≤100 µsec.

9.

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

10. Current limit point expressed as a percentage of full rated load current.

11. For models with two positive outputs the envelope specification for the design is that each output voltage is limited to the

range 1V to 5V.

12. Although operation at temperatures between +85°C and +125°C is guaranteed, no parameter limits are specified.

13. Meets the derating requirements of EEE-INST-002 – except for ceramic capacitors with voltage stress below 10V will

minimum be rated at 50V and a minimum load of 20mA on each output.
