AFL28XXS Series

Dynamic Characteristics -55°C < T

Notes to Specifications:

1.

Parameters not 100% tested but are guaranteed to the limits specified in the table.

2.

Recovery time is measured from the initiation of the transient to where VOUT has returned to within ±1.0% of VOUT at 50% load.

3.

Line transient transition time

≥ 100µs.

4.

Turn-on delay is measured with an input voltage rise time of between 100V and 500V per millisecond.

5.

Current limit point is that condition of excess load causing output voltage to drop to 90% of nominal.

6.

Parameter verified as part of another test.

7.

All electrical tests are performed with the remote sense leads connected to the output leads at the load.

8.

Load transient transition time

≥ 10µs.

9.

Enable inputs internally pulled high. Nominal open circuit voltage

≈ 4.0VDC.
